Are you thinking they can complete their entire campaigns without ever debating one another in person? Short of another outbreak of Covid and the need to resort to a Zoom debate, how would voters respond if B & T don't have a live meeting? And T, of course, would be taunting B and holding him up to ridicule if B
sits this out.
Since seeing the State of the Union Address, I have more confidence that B can hold his own and perhaps come out even or better. If challenged to, he should debate.
