General Discussion

I stated very clearly that 21 incumbent presidents have been re-elected and 10 have not. That's a total of 31, not 45. Some presidents, like Teddy Roosevelt, didn't seek re-election, some died of natural causes while in office, 4 were assassinated.

10/31 is a failure rate of 32%. However that history may apply to the present case, you're making an emotional argument and changing the numbers rather than simply acknowledging it.

The people who prefer a replacement for Joe Biden are doing it because they feel it will give them a better chance of beating the convicted felon, not because they want to concede to him.
