But if we woke up tomorrow and trump didn’t exist, they would all be gone

They existed before Trump with the tea party, they will exist after him. The far right also exists in other countries

the kamala harris campaign

Right, not centrist. They just aren’t as right as the competition

“far left” israel palestine types

Not a left or right issue, you will find people on both supporting both sides

Generally, i think the left, currently is a lot more cohesive than the right

This has never been the case, the lack of cohesion is why right wing governments are more popular despite not being popular in a population. People will just not vote because there is no coheson on the left. Meanwhile the right will always come out to vote, even when they don’t agree with their candidate
