A lot of undecided African American voters. I think they will break for James.
Why? I've written this elsewhere but his overperformance with them last time was much smaller than with other demographics and I've not seen a decent pitch for why he'd be significantly more appealing to black voters specifically this time around (relative to other MI voters, that is).
Why would they be undecided this late in the game? A lot less AAs are undecided in the Trump-Biden matchup.
Perhaps because people simply don't pay as much attention to downballot races.
I'd be willing to bet that if you asked Texans to name their two senators, you would get a large amount of "wait, is Ted Cruz a senator" and "I know Ted Cruz, but...I just can't think of that other guy's name."
