If Biden doesn’t plan to debate , why should Trump ? It’s his call. Let the peons squabble amongst themselves . They alone are sufficient to convince the people they shouldn’t waste their precious votes on any of them.
Biden doesn’t have competitors that can win. He’s the incumbent. I don’t believe we had debates for the 2020 election either. Incumbency usually doesn’t.
When has an incumbent President ever debated in a primary?
Didn’t happen in 2020 either. None were even attempted to be organized.
