Every poll says the same thing: most "likely voters" are fed up with the poor job President Biden is doing. The surveys also indicate Donald Trump has a negative image as well due to his personal style.
Neither situation is likely to change before the primaries begin in early 2024. Mr. Biden is incompetent, and Mr. Trump is polarizing in the extreme.
So both political parties have a massive problem. There is no one visible enough to replace Biden, and few democrats would challenge him anyway for fear of angering the left wing, which has Biden in its pocket.
On the right, Trump remains the front-runner over Governor DeSantis, and the MAGA voters are incredibly loyal. However, there are not enough of them to propel Donald Trump back into the White House, assuming he wins the most primary votes.
Taking emotional politics out of the picture, the smart play for the Democrats would be to have Joe Biden hang it up and usher in an open primary process where a number of candidates could be evaluated.
The intelligent play for Trump and DeSantis would be to agree to run together, the Governor taking the Vice-Presidential slot by agreement with Trump.
However, both of those situations would require egos to be put aside.
Place your bets now.
