My best suggestion for Biden at this juncture: Have a press release typed and ready if Trump does back out to the effect of “I called Trump’s bluff, I named a time and a place, and he backed down. As such, I consider the subject of debates over and done with. I will not agree to any debates he offers because I have no guarantee that he will not get scared and back out of those at the last second as he did this one. He can make whatever excuses he likes, call me whatever he likes, but the American people can see that when pressured to perform he duck and ran. We’re done here.”
