I’m not American to vote so disregard me, but I will say that I don’t personally believe in voting by nominal ‘tribe’.
No one gets my vote by sharing my ‘femaleness’ or nominal religious affiliation.
I vote for a politician on the basis of the policy platform they run on.
(Regarding pro-life, my country doesn’t have a major party that permits discussion of pro-life views. If we did though that’d move me their way. Since we don’t I do pay attention to other issues… but America does still have a major party willing to fight for pro life legislation so if I lived there I think I’d have to vote for them. Almost especially because I live in a country that’s already too far gone, it’d give me hope to see America hold out longer and maybe even turn the tide.)
I’d also echo what others have said which is to remember that you don’t have to believe either candidate is perfect. (It’d probably be weird tribalism if you believed they were.) Remember that you’re voting to effect some kind of policy impact (that’s what politicians are for) and consider each candidate/party on the basis of policy platform (and plausibility of actually working towards the same). My thoughts, anyway.
