The problem I have with the lesser evil argument is the assumption that we're dealing with the real thing. We're not. Trump may be a career criminal, but he isn't pure evil. He's just a flamboyant arsehole who has largely enacted typical GOP policy (tax cuts for the rich etc).
Locking refugee kids up was a policy initiated by Obama, & no centrist would think to call him evil. Both parties support a health system that is wasteful & actively kills the poor. Invading or sanctioning foreign countries that displease the US is similarly bipartisan.
The choice is rarely between outright evil & some flawed centrist but between two varieties of the establishment (even Macron vs Le Pen falls into this category). This is a managed "choice". It may not be rigged, in the manner of Russia or Belarus, but it is still constrained.
By all means vote for the least-bad option, but don't try & justify it with vapid talk of "evil". That is merely a spectre employed to discipline ambition.
