Ordinarily, it& #39;s easy to dismiss Biden& #39;s gaffes b/c they& #39;re priced into voters& #39; expectations. But this one might be different: black voters are the margin in 5 of the 6 most critical Electoral prizes (FL, MI, NC, PA, WI) and Biden just handed Trump a new three-word fall meme.

Biden& #39;s base in the primaries was older African-Americans, who will vote for him overwhelmingly. The challenge for Biden remains younger black voters (esp. male) who liked/voted for Obama, didn& #39;t vote in 2016 and don& #39;t identify w/ either political party.

Trump has next to no appeal or credibility w/ this demographic. But his campaign’s goal will be to drive down Biden’s appeal w/ young black voters (1994 crime bill, Anita Hill, busing, etc.) to blur distinctions & depress turnout, as in 2016. It can work, and margins matter.

In other words: will “you ain’t black” be forgotten by the news cycle in a few days? Of course it will be. Should Dems be concerned about the Trump camp’s potential to weaponize it in targeted digital ads this fall? Absolutely.

I& #39;m not talking about one gaffe producing some seismic shift in the black vote. Black voters are going to reject Trump by a massive margin.

But Biden winning 91%-7% w/ 60% turnout vs. 88%-10% w/ 55% turnout could be the difference in these key states. It was the margin in 2016.
