I fully expect Joe to drop any debates and the lame stream media will with a straight face deliver whatever spin Bidens handlers supply them. However, debates have been a fixture of the Presidential race since Kennedy and Nixon and to suddenly drop them for some flimsy reason likely related to COVID will not play well. The COVID excuse will likely raise questions about a Bidens overall health. The excuse of Trump is mean, a liar etc. will be seen as a cop out. Biden is between a rock and a hard spot. The debates will be a disaster and not doing them could be equally as bad.
Joe Biden being caught between two very bad choices is not a new situation for him. What can be relied upon, if given a choice, Joe Biden will inevitably pick the worst possible.
This time, it will be for himself, not the country as a whole.
