Nice gotcha, but she’s not going to win, so she’s not practically a choice. “Vote for the lesser evil” is a good shorthand, but it’s still shorthand; the philosophy is to vote in a way that will cause the least harm. If your candidate has no chance of winning, then you aren’t doing that, since your vote is roughly equivalent to not voting. Voting for a third party only makes sense if you weren’t going to vote at all, and in that case it’s a better choice but still not the best one. Hope that helps clear up any confusion around the lesser evil sentiment.
