If every third-party voter voted for either Trump or Clinton

If everyone who didn't vote for Trump voted for Clinton:

324 - 214

If everyone who didn't vote for Clinton voted for Trump:

355 - 183

This map just goes to show how strongly the third-party voters affected the election, especially in the Southwest and Midwest. Obviously, not every third party voter would've voted the same way but is interesting to see how much a small swing (except for NM and UT, the most percentage increase a candidate would get is around 5-6%) affects the EC so greatly.

Clinton would have also lost Virginia. She only got 49.75% of the vote.

There, it's fixed. I should've taken a closer look at VA, but I didn't read the <1% votes.

Except for Utah, those maps are probably the respective ceilings for both parties going into 2020.

Not really.

Except for Georgia in a landslide, that is probably the best the Democrats can do if you take away Utah. Realistically speaking, the map for Republicans is probably their ceiling (although DE, NJ, CT, and RI could flip in a landslide).
