What I think it is happening is that bettors realize there is a silent majority who does not attend to neither leftist events nor MAGA gatherings, the so called moderated voters, they are more pragmatic and do not go along with whatever of the things Trump says, political related or in relation to the charges he is facing.
That is why Republican candidates in the mid terms under performed, on the news you only see fanatics but those who stay calm in their homes also vote and they do it in a more rational manner, there is where the Biden's changes of winning come from, from normal people who may not agree on several policies of Biden but approve his economical advances.
You mean "normal" people. Because any normal person would see right through this situation and would not want either side. This is basically just trying to get votes by playing into the hands of other side and I think that's not a good way.
Any candidate that is a normal person who just says ordinary stuff like more jobs, better healthcare, cheaper drugs, better education, more pay to teachers, better pay to truckers, military power, and all kinds of cliche things presidential candidates said for the last 200 years, I bet that person would actually have a high chance of getting the win. When both sides are crazy like this, I can say that it is not going to be easy choice, everyone would look into this as a "better my bad than your bad guy" type of deal.
