Why Trump won is an interesting topic. There is a mixture of reasons but I think high up there was Biden pulling out last minute and Kamala being unpopular with little time to do a campaign. She also had the backfoot of having been in power while there was inflation and support for the Gaza genocide. Therefore Trump won less then Kamala lost.

There is a subreddit dedicate to people both democrats who refused to vote, as well as Trump voters whose policies as promised would severely harm them and their family's interesf (severe as in life/death). Why did they vote against their interests.

For example anyone on any kind of benefits, or whose mum and dad are, vets or if your cousin or uncle is one, Latino, even if you are from a long line of american citizens you may have friends who are 1st gen. More generally anyone not white, male and in the top 5-10% of wealth. Because tariffs won't be good for poor people. And poor is probably: under $1m assets.

Google trends for tariffs surged after the election. People voted on feelings. Anger, despair or some sense of "Trump means them not me" or maybe "He is successful in business so he must be good".

Unfortunately the rational thing to do often sucks eggs!
