You're right, I am confused. It was clear what was going on under his first term... You guys voted him back in!!
I used the word "endorsed", not "voted". The distinction does matter.
Only about 25% of the voting age public voted for Trump. Almost 25% of the voting age public weren't registered to vote, perhaps some of them wanted to vote but couldn't, so let's use the registered voters as the denominator. 75.8% of them voted; roughly one third for Trump, one third for Harris and one third didn't vote.
Choosing not to vote against a likely outcome is an endorsement of that outcome in my opinion.
