Why do Republicans think that Donald Trump being re-elected will save them ?

I just see chaos. I see more racial tensions. More mass shootings. More trade wars. I see a great divide. There will not be any peace as long as Trump in office. I feel there will be a massive overkill and the Dems will be in the same position they were in like they were after Bush number 2. Its going to be messy. And Trump will be ignored in the history books. What do you think. 🙂
