I wanted to share a few thoughts with you about this email from a TPM Reader from Maine which I posted last week. It crystallized a few thoughts I had about the Maine Senate primary and politics more generally. In general, I’ve always been pretty against purity tests in politics, though the label “purity tests” somewhat prejudges the question. TPM Reader JU tells us that she didn’t rank Graham Platner first (Maine has ranked choice). But that she wasn’t disappointed that he prevailed. She also believes that most of the morality tale interpretations of what happened in the primary miss what’s driving Maine voters. It’s not that they don’t care about Platner’s baggage, or that they’ve adopted some Trumpian cynicism. They just have a different understanding of character tests in politicians mount to. (You can read the post here.)

Basically I agree with JU. But I want to abstract this out, to at least a degree, from Platner’s specific issues because I know people have strong feelings about that race and the specific accusations that were made against him. Possibly the argument I’m making is valid but I’m misapplying it to Platner. But I’m trying to articulate a more general point rather than relitigate the Platner primary.
