Would be nice but I'm very skeptical about it ever happening. If it's a pact, not a federal law that can stand up to a constitutional challenge, then it's unenforceable.

iirc, the Electoral College is in the Constitution. It would require an amendment to get rid of it. In the Senate, and the sparsely populated states, that would be a loser. Washington DC has more population than Wyoming, but Wyoming gets two Senators. Washington gets none. The plains states would never give up their overweighted representation.

That's obviously true. But the "popular vote pact" is an idea that's meant to circumvent the constitutional electoral college. If a group of states that control more than half of the electoral college agree to assign their electoral college votes to the national popular vote winner, regardless of the vote in each particular state, then the winner of the popular vote will become president. There's nothing Wyoming or all the minority states can do about it. If you support electing the winner of the national popular vote for president, it's a neat idea. But I'm saying that it's unenforceable. Any state that joined the pact could renege on it in any election.

Right now states controlling 250 electoral college votes have joined the pact. You need 270 to elect a president. Imagine that Texas has turned blue and decided to join the pact. With 40 votes from Texas the pact could go into force. Now let's say that in 2028 we have a very close presidential election. The Democrat wins the popular vote. But Texas reverts back to being a red state, and decides to leave the pact, thus getting the Republican candidate to be president. There's nothing the other states in the pact could do about it.
