Interesting thought - but i would prefer to not lower the Conservatives to the level of DPST behavior. 
Trump's impeachment is part anger over loss in Nov. 2016, and part over Clinton's impeachment. 
i worry less about warren leading a Constitutional amendment to cancel the EC - unlikely - than the National Popular vote Interstate Compact.  This would obviate the EC as designed to function.

  The 
National Popular Vote Interstate Compact (NPVIC) is an 
interstate compact  to award member states' presidential electors to the candidate that  receives the most votes nationwide. The NPVIC would go into effect if  states representing at least 270 electoral college votes adopt the  legislation.
[1][2]  
As of October 2019, 14 states and Washington, D.C., adopted legislation to join the National Popular Vote Interstate Compact. Together, they represent 187 Electoral College votes. Colorado, representing nine electoral votes, passed NPVIC legislation, but the law was suspended pending a vote on a veto referendum in 2020.[1][2] 
Article II, Section 1 of the 
U.S. Constitution  gives states the authority to determine how their electoral votes will  be awarded: "Each State shall appoint, in such Manner as the Legislature  thereof may direct, a Number of Electors." This compact does not  abolish the electoral college system; rather, the compact awards all of  the electoral votes from the member states to the candidate who receives  the most votes nationwide.
[1] 
   History
 Most states award all of their electoral votes to the candidate who receives the most votes in the state. In 2016, 
Donald Trump won the presidential election with 304 electoral votes but 
Hillary Clinton  received the most votes nationwide. The 2016 election was not the only  instance in which the winner of the presidential election did not  receive the most votes nationwide; it happened in five of the 58  presidential elections in U.S. history.

 In Colorado, the state legislature passed NPVIC legislation in 2019, which 
Gov. Jared Polis (D) signed on March 15, 2019. Rose Pugliese and Don Wilson filed a 
veto referendum  against the legislation, and collected signatures for the law to appear  on the ballot. The veto referendum was certified for the ballot on  August 29, 2019, which had the effect of suspending the law until voters  decide the law's fate at the election on November 3, 2020.

Text of the compact
 The legislature of each member state passes the laws with certain and  modifications, but the core of the legislation remains the same. 
  
Article I: Membership
 Any State of the United States and the District of Columbia may become a member of this agreement by enacting this agreement. 
 
Article II: Right of the People in Member States to Vote for President and Vice President
 Each member state shall conduct a statewide popular election for President and Vice President of the United States. 
 
Article III: Manner of Appointing Presidential Electors in Member States
 - Prior to the time set by law for the meeting and voting by the  presidential electors, the chief election official of each member state  shall determine the number of votes for each presidential slate in each  State of the United States and in the District of Columbia in which  votes have been cast in a statewide popular election and shall add such  votes together to produce a “national popular vote total” for each  presidential slate.
- The chief election official of each member state shall designate the  presidential slate with the largest national popular vote total as the  “national popular vote winner.”
- The presidential elector certifying official of each member state  shall certify the appointment in that official’s own state of the  elector slate nominated in that state in association with the national  popular vote winner.
- At least six days before the day fixed by law for the meeting and  voting by the presidential electors, each member state shall make a  final determination of the number of popular votes cast in the state for  each presidential slate and shall communicate an official statement of  such determination within 24 hours to the chief election official of  each other member state.
- The chief election official of each member state shall treat as  conclusive an official statement containing the number of popular votes  in a state for each presidential slate made by the day established by  federal law for making a state’s final determination conclusive as to  the counting of electoral votes by Congress.
- In event of a tie for the national popular vote winner, the  presidential elector certifying official of each member state shall  certify the appointment of the elector slate nominated in association  with the presidential slate receiving the largest number of popular  votes within that official’s own state.
- If, for any reason, the number of presidential electors nominated in  a member state in association with the national popular vote winner is  less than or greater than that state’s number of electoral votes, the  presidential candidate on the presidential slate that has been  designated as the national popular vote winner shall have the power to  nominate the presidential electors for that state and that state’s  presidential elector certifying official shall certify the appointment  of such nominees. The chief election official of each member state shall  immediately release to the public all vote counts or statements of  votes as they are determined or obtained.
- This article shall govern the appointment of presidential electors  in each member state in any year in which this agreement is, on July 20,  in effect in states cumulatively possessing a majority of the electoral  votes.
Article IV: Other Provisions- This agreement shall take effect when states cumulatively  possessing a majority of the electoral votes have enacted this agreement  in substantially the same form and the enactments by such states have  taken effect in each state.
- Any member state may withdraw from this agreement, except that a  withdrawal occurring six months or less before the end of a President’s  term shall not become effective until a President or Vice President  shall have been qualified to serve the next term.
- The chief executive of each member state shall promptly notify the  chief executive of all other states of when this agreement has been  enacted and has taken effect in that official’s state, when the state  has withdrawn from this agreement, and when this agreement takes effect  generally.
- This agreement shall terminate if the electoral college is abolished.
- If any provision of this agreement is held invalid, the remaining provisions shall not be affected.
Article V: Definitions
 For purposes of this agreement,  
 
- “chief executive” shall mean the Governor of a State of the United States or the Mayor of the District of Columbia;
- “elector slate” shall mean a slate of candidates who have been  nominated in a state for the position of presidential elector in  association with a presidential slate;

- “presidential elector” shall mean an elector for President and Vice President of the United States;
- “presidential elector certifying official” shall mean the state  official or body that is authorized to certify the appointment of the  state’s presidential electors;
- “presidential slate” shall mean a slate of two persons, the first of whom has been nominated as a candidate for President of the United States  and the second of whom has been nominated as a candidate for Vice  President of the United States, or any legal successors to such persons,  regardless of whether both names appear on the ballot presented to the  voter in a particular state;
- “state” shall mean a State of the United States and the District of Columbia; and
- “statewide popular election” shall mean a general election in which  votes are cast for presidential slates by individual voters and counted  on a statewide basis.
Arguments
 The 
Congressional Research Service  published a document on the NPVIC, which contained arguments for and  against the compact. The following are excerpts of the arguments:
[4] 
 Support
 - "Proponents of the NPV initiative arguably share the  philosophical criticism voiced by proponents of direct popular election,  who maintain that the electoral college system is intrinsically  undemocratic—it provides for “indirect” election of the President and  Vice President."
- "NPV advocates also assert the compact would provide a practical  benefit to states that tend to be noncompetitive in presidential  elections and which therefore receive fewer campaign visits by major  party candidates. With “every vote equal,” NPV maintains that  presidential and vice presidential nominees and their organizations  would need to spread their presence and resources more evenly as they  campaigned for every vote nationwide, rather than concentrate on winning  key “battleground” states."
- "NPV advocates also maintain that the concentration of campaign  resources, advertising, and candidate appearances in battleground states  depresses turnout in “flyover” states, where candidates make few  campaign appearances."
Opposition- "Some argue that it is unconstitutional or “anticonstitutional,”  that is, contrary to the Founders’ intentions and the spirit of the  nation’s fundamental charter."
- "The existing electoral college system, NPV skeptics might also  assert, is a fundamental element in the federal constitutional  arrangements established by the Constitution. Fearing “the tyranny of  the majority,” the Founders established a system of government that  provides checks and balances designed to restrain the majority and  secure minority rights."
- "Successful nominees are compelled under this system to present a  broad political vision that commands nation-spanning “concurrent  majorities” and appeals to the great variety of Americans. ... The NPV  initiative, they could claim, would discard the Founders’ intentions in  favor of what they consider to be a flawed “majoritarian” presidency  that would ill-serve a continent-spanning and profoundly diverse  republic."
Constitutionality of compact
 The 
Compact Clause of the 
U.S. Constitution  says that "No State shall, without the Consent of Congress... enter  into any Agreement or Compact with another State..." Proponents of the  NPVIC argue that the compact is constitutional, whereas opponents argue  the compact is an unconstitutional violation of the Compact Clause  without Congress' consent. 
 
Constitutional
 Jessica Heller, a legal writer at 
FairVote:
[5] 
    “   On its face, the Compact Clause does ostensibly prohibit any compact  between states lacking congressional consent. However, the Supreme Court  has definitively stated that “not all agreements between States are  subject to the strictures of the Compact clause.” U.S. Steel Corp. v.  Multistate Tax Comm’n, 98 S.Ct. 799, 469 (1978). Rather, the prohibition  is only directed “to the formation of any combination tending to the  increase of political power in the states, which may encroach upon or  interfere with the just supremacy of the United States.” Id at 468,  quoting Virginia v. Tennessee, 148 U.S. 503, 519 (1893). Therefore, if  the NPVC does not infringe upon federal supremacy, it does not require  congressional consent. By that logic, the NPVC is certainly valid as it  stands. ...  
Electors are chosen by the state, and are therefore state, rather  than federal officials. The states’ plenary power to choose its  electors goes to the heart of a republic government, a government whose  leader is chosen by the people. Requiring congressional approval would  directly infringe on that power, meaning that any claim that the Compact  Clause would require such approval for the NPVC would put the Compact  Clause and the Guarantee Clause in direct conflict with one another. ... 
Each state’s votes would still be counted, and each state would  have an equally important role in choosing the President. Nothing in the  NPVC would alter non-compacting states’ sovereign right to choose its  electors. Therefore, any Compact Clause challenge to the NPVC should  fail.
[6] 
   ”   
 
Unconstitutional
 William G. Ross, a law professor at Cumberland School of Law at Samford University:
[7] 
    “   Although the US Supreme Court has concluded that the Compact Clause  does not require Congress to consent to compacts that affect only the  internal affairs of the compacting states, it has indicated in US Steel  Corporation v. Multistate Tax Commission that the Compact Clause  requires Congress to consent to an agreement that “would enhance the  political power of the member States in a way that encroaches upon the  supremacy of the United States,” or “impairs the sovereign rights of  non-member states.” ... 
Although the compact would not violate the letter of the  Constitution since it would retain the Electoral College and would not  alter the method by which electoral votes are assigned or change the  number of electoral votes that any state has, it would jettison the  federalist structure of the Electoral College to the extent that the  popular vote rather than the votes of individual states would determine  the outcome. The compact’s reduction of the Electoral College to an  empty shell would therefore thwart the intention of the Framers of the  original Constitution and the framers of the Twelfth Amendment, which  reformed the Electoral College in 1804, since the Constitution clearly  contemplates that electoral votes will be cast by the states as states  rather than by the states as collective or compacting entities.
