Who Are they Messaging?

[youtube https://www.youtube.com/watch?v=Ev3BGqGuSfQ&w=1280&h=720]Who is Trump targeting with this ad? I can't imagine him picking off many black votes from Biden, especially while he's got his "suburban housewife" campaign underway--but I could see how some of those suburban housewives might feel reassured that Biden is just as racist as they are and vote for him instead of Trump.I'm seeing a lot of "Harris isn't really black" messages from Republicans too, in part because she's partly South Asian, in part because one of her Jamaican ancestors is said to have been a slave owner. Again, wouldn't that reassure rather than frighten wavering Trump voters, at least that substantial majority of them who have issues with authentically black black people (whatever in the world that is supposed to mean)? And don't most African Americans have slave owning ancestors?My guess is that these ads are designed solely to depress Democratic turnout. Between that, bankrupting the post office, closing polling stations in cities, preemptively disqualifying the few mail-in ballots that make it through the gauntlet, and energizing his Second Amendment/born-again/biker/boat-parading core, he hopes to squeak through with a popular minority again.But then what? So he can continue to preside over a prostrate economy, an uncontained plague, and massive civic breakdown? So he can become even more of a spectacle than he already is, as his dementia progresses, state-level investigations and prosecutions multiply, and the climate and Covid crises intensify?Honestly, I don't know why either of these men would want to be president. But I must say, I feel a lot better about Biden than I did a day ago.
