re: #7 Wendell Zurkowitz ((slave to the waffle light))

Are there any high-profile primary challengers?

And there would be no point in a debate between DJT and Biden.

Recall that Trump did not even see fit to attend his successor’s inauguration.

Even with high profile challenges, I don’t think an incumbent president has participated in a primary debate. Ford didn’t in ‘76, Carter didn’t in ‘80, Bush didn’t in ‘92.
