I hope I'm right, but I think this guy is in this to help draw apart anti DeLay voters. I know I'd get a few people to run against me if I was Tom.
The other two people running in the GOP primary are loony and very possibly Democrats. Thode will not attack Campbell, and, in fact calls him a legitimate candidate. Campbell is saying the right things and is obviously a Republican.
Given the field of three, DeLay would have easily won my vote. I'll be watching Campbell. If he's the real deal, I may vote for him. I do, however, agree with Thode's assessment that DeLay will likely comfortably win the primary.
I think he's also positioning himself to win the nomination, and likely the seat, if Delay is forced to withdraw from the race by a bad court decision.
