I don't understand the "if the EC was abolished, Dems would win everything" talking point. Trump didn't lose the PV by that much, people. 2004 wasn't that long ago.
Remember that as recently as 2012, people were saying the EC favored Democrats. This could easily be the case in 10 years when states like AZ and GA become D - leaning, and Texas is a tossup.
Yeah, the popular vote isn't Safe D. Maybe if Trump had run a better campaign, he could have won the popular vote. Republicans have also won the popular vote in a majority of House elections in the 21st century, and won it in 3/5 House elections that coincided with a presidential election (including the 2016 election). While Democrats probably do have a slight advantage, it's not a big one.
The reason the Electoral College should be abolished is not for partisan reasons but because it's an undemocratic system that does not accurately translate the will of the people into election results and makes some votes matter more based on the arbitrary distinction of which state people live in.
