Honestly, dropping out this late was kind of a genius move, even if it was unintentional. The Trump campaign is twisting in the wind. They were all in to fight Biden. Now it’s an old man against a woman who isn’t young, but also doesn’t look 59, and is clearly just far more intelligent and far more just cognitively able than Trump.
And the best attack Trump has been able to come up with is “she turned black all of a sudden.” Which he said to a bunch of black people.
