My gut feel has always been that removing the electoral college would hurt the blue team and help the red team. Logic:

The popular vote is basically split evenly today (the usual talking point, 2016, was 62,984,828 Trump, 65,853,514 Clinton). 2020 and 2024 had similarly small-ish margins.

So take 2016: if we’d had a normal election cycle, and then the day after voting said “hey guys let’s do this based on the popular vote!”, Clinton would have won. But that’s not how it would be; both sides would know of this change for at least the full election cycle.

So now you start with a roughly 50/50 split voting base, with many Democrat votes coming from big cities and many Republican votes from Middle Of Nowhere, Kansas.

You win the upcoming election by gaining votes.

Republicans go energize the voters in New York, LA, SF, Seattle, Austin, etc, who are not voting today because they (correctly) know their vote doesn’t matter. They maybe change some bit of their platform to appeal more the big city voters. They can pick up millions of votes in relatively few places.

Democrats have to go win votes from Middle Of Nowhere, Kansas. Or more accurately, 500 small towns in Kansas, to pick up a few hundred thousand votes. There isn’t nearly as much of a depressed Dem vote in red states, simply because red states have small populations (see “land doesn’t vote!”). It’s an exponentially harder problem. While Democrats are trying to convince Uncle Rupert that FOX is lying to him, Republicans are filling Madison Square Garden in NYC with closeted Republicans and telling them their vote will count for the first time ever.

I just don’t see how abolishing the electoral college doesn’t backfire on Democrats. How wrong am I?
