That would be nice, but unless you're in a state that's comfortably blue (or red) and is winner-takes-all, that's a bad idea. That's how you get trump back in office.

By voting for someone other than blue, you're reducing the number of votes blue gets. While your intention may be good (trying to get an actual left-winger into office), the result is that it's one less vote for blue, which is one less vote team red has to overcome. Too many of those and you get team red, aka trump, back in office. Despite your good intentions, you will have contributed to the problem.

If we weren't staring down the barrel of a loaded gun, I'd say "go vote 3rd party if you want, knock yourself out." However, we're looking at the end of democracy in the US. This may legitimately be the last election you can vote for any party other than team red.
