Congress doesn't have to pass it. Under the Constitution, the states can have compacts. The states also determine how they will allocate their electoral votes.
Thus, we should all be educated enough to resist such erosion of a properly conceived and well-balanced system. People would to well to read the Federalist Papers...
If only that were the case. Most people are ignorant when it comes to our history and the Constitution. The direct election of the President has great appeal to the uninformed along with the Dem party, which is changing the composition of the electorate thru mass immigration.
You are sadly right. This is just part of the system to destroy our republic fully and totally. We’ve been on a march toward this ever since the country was founded. First we had direct election of the Senate. Then we had to have enfranchised women. Then enfranchised 18 year old people. The only thing left that protects the smaller, weaker, mostly conservative states from total elite/liberal domination. Unfortunately, the “people” fully support direct elections when they are framed as “liberty” and “democracy.” If this continues, and the Electoral College is abolished, there will never again be another conservative or even “less liberal” President. I hope that Trump’s election demonstrates that to many people so that we can fight, but I doubt it will stop the march to direct elections.
