Messing with the Electoral College is a constitutionally stupid idea. If you want to fix what’s wrong in Washington, D.C., start by repealing the 17th Amendment, which robbed states of their representation in Washington by taking the election of U.S. senators away from state legislatures where it belongs.
Then, demand that Congress do what it historically did after each US. Census until 1920, which was to vote to increase the number of representatives proportional to population growth. In the original 1789 Congress, each member of Congress represented 60,000 people. By 1900 that had crept up to about 100,000 or so people per House seat.
Since then, the size of the House has not effectively increased with population, and so representation has been seriously diluted down to about 800,000 people per seat. That’s not “representation” at all in my opinion.
Only after fixing those to progressive/Woodrow Wilson-era mistakes should we consider doing anything to the Electoral College.
