Reposting my own comment here:
I live somewhere with 2 Republicans on the ballot for one seat with no write in line.
I could have not voted at all on that item, but that wouldn't have helped anybody but the worst of the two candidates.
I poured through more interviews and candidate statements from these two trashy people than any other candidate I voted for, just to find the one that was the least evil.
I still hate them both, but I voted for one to try and stem the bleeding because that's how our Democracy works.
And adding a quote from Rage Against the Machine's Tom Morello:
But in any and every contested race, as my mom Mary Morello always said, we have to fight the fascist every which way we can, recognizing that even if there's but an inch of difference between two candidates, there are a lot of vulnerable people who could be greatly harmed in that inch.
