@freemo It’s possible, but since the Bull Moose party in 1912 it doesn’t look like a third party has gotten a significant share of the vote and the Whigs appear to have disappeared in 1860 or so.
I’m seeing Kennedy, Stein, and West as third party candidates (with apologies to any I’m missing), I can’t say I’m affirmatively enthused about any of them. None of them are likely to crack 5% unless something dramatically changes.
In a normal year, where there were just two candidates that I didn’t like I’d be more inclined to vote third party (and I have in the past). For me (and speaking only for me) Biden / Trump is a choice between bad and catastrophic. My personal judgment is that I’d prefer bad over catastrophic but everyone gets to make that choice for themselves.
None of that is to tell anyone else what to do or how to vote, it’s just my thought process.
