He has the numbers to back this up. I think we also lost Craddock and Mason as a result of horrible showing in NOVA even though there are not direct numbers to prove that. I do think some candidates could have helped themselves (Craddock and Marrs by shutting up and Black by not sending out plastic fetuses). Even so, you cannot overcome a top of the ticket beatdown like we saw on election night.
As I have said before, I believe we can regain a few of these seats; namely the 32nd 67th and 68th.
