This Carroll sounds like a fantastic person from what I've seen about him so far, but I'd really prefer he primary one of the useless House people or Scott -- Lindsey Graham has been a fantastic Senator so far and I'd much rather he stay. It's a shame Tisei didn't win in 2012 -- gay Republicans are quite underrepresented in Congress. At least we have Cantor.
So, basically just the exact opposite of what Marokai said
I've never heard any insinuations about Eric Cantor.
Regardless,
you still have David Dreier, Aaron Schock, possibly Adrian Smith.
