WIBTAH If I didn’t vote for my boyfriends step mom?

So I (19F) have been dating my boyfriend (20M) for a bit over 2 years now. We have a really good relationship overall, but our biggest hurdle has always been his dad and step mom. From the beginning of our relationship they haven't seemed to like me very much, but also have seemed to like me a lot at the same time. His dad is always inviting me over for dinner, telling him that I’m a keeper and such, but then when I’m not around it’s like he hates me.

One time after Christmas time, he asked to have a chat about my “behavior” to my boyfriend. But never mentioned anything to me. I’ve also heard from my boyfriend and his siblings that he’ll make backhanded comments about me behind my back. If I’m doing something wrong that is upsetting him, why isn’t he coming to me to talk about it? Because I can understand if I did something wrong, but I’m being given no chance to right it.

anyways, an election is coming up soon in my town and my boyfriends step mom is running for an office. She has never been nice to me, not necessarily mean or anything like that, but we’ve never really had many one on one conversations. Especially recently though, anytime I’m around her, she doesn’t really talk to me directly. She‘ll only really talk to me when she’s correcting me on something. Specifically when it comes to her campaign, she definitely has not talked to me at all about it. I have no idea what she plans to do in office or any of that.

So I’m at a bit of a crossroads here. I feel this sort of obligation to vote for her because in a sense, she is family, and I would almost feel responsible if she lost. But on the other hand I feel like I have reason not to, I don’t know her campaign at all, and she’s not someone I would vote for if I didn’t know her.
