or the phrase lesser of two evils...

Candidate A - will do X, Y, Z all in ways I think are the best Candidate B - will do A, B, C which I prefer less than X, Y, Z but in the grand scheme likely impact my day to day life little. Candidate A - also supports (or is supported by) people / movements that actively make my life harder and piss me off.

That's not cutting off my nose that's deciding I can live with a less optimal solution to some problems to avoid something that pisses me off massively from growing more powerful
