Biden can't prove it in the polls. It's insane that Trump is in the race. It's more insane that Biden isn't 20 points ahead of him but instead Biden is behind. Biden wasn't the incumbent in 2020 and was 4 years younger.

Something's wrong with this picture and you need better answers then that to explain it.

BTW, I updated my 1st reply. You may want to check it out. Sorry I did it piecemeal. I had to verify some things. Also Reagan's 1st 1984 debate was him reciting Shakespeare compared to Biden's performance. You need to go back and check them both.
