IMO there is not much tRump can do to add new voters at this point.

4. Maybe Trump can't win voters, but make Kamala sure doesnt lose them

This all boils down to the 100,000 people in swing states. Not the other 300,000,000+.
Those 100,000 people will be influenced by the most ridiculously low level stuff, which includes all types of media and whispers. Democrats across the country - not just the campaign and the candidate - need to stay mature and professional about this because who knows what turns off a swing voter in Wisconsin. Let Trump and team be their own worst enemies since they cannot help themselves but be self-mutilating.
