They probably won’t vote for Harris, but they won’t vote for Trump either.
This is actually possible. There’s a “don’t tread on me” type that has been using their yard as a political billboard for years and i just recently noticed that while they’re still anti- our current Democrat governer, they took down their pro-Trump stuff as well. Now there’s some sign about Jill Stein that’s up but seems a lot less flamboyant.
