I think the impact is negligible.
Congressional primaries are very low turnout affairs.
Totally agree.
National tea party groups sat this one out, so they can't take much credit. This is kind of the opposite of a presidential primary, with the locals punishing a national figure. This was the tea party operating on a grassroots local level.
I'm not sold on this part. Talk radio was pretty active in promoting David Brat.
The tea party has been effective at winning a few upsets, but that's not enough to win a presidential primary.
Totally agree here, too.
