I don’t know if Trump thinks this will help (it may at the margins), but really the only demo where he’s relatively weak is white women. He’s at 90% GOP approval and has high marks from minorities, relative to your average Republican.
But, I agree: savaging a qualified, articulate woman - a mother of 5 + 2 adopted minority kids is not a good look. Making vulnerable red state donks on the ballot this year walk that plank is going to be horrible for them.
If they vote her down, they likely lose seats next year and get Pryor instead.
Yes on Pryor.
