I'll put in a word for Helvey, though he'd prolly be #3 on my list. He says he's a conservative, and I've met the guy, and I think he's a decent guy. I've met his campaign staff, and they seem like nice folks as well. Nice as in honest. Is there any proof he's a conservative? No, no track record, although he didn't hesitate to max out to the BushCheney04 campaign (best $2k he's spent yet, IMO). Is there any proof he's a moderate or liberal? No.
Of course, to be safe I'd go with Vernon (first, although sometimes he gets a little RonPaul-ish) or Tabor (second, although he's so . . . "Soy Boy"-ish). There's no question how they would vote in Congress, maybe a little different but both stellar, supporting Christian conservatism.
Third would be Helvey; my impression is that he is sincere, and that he'd be a good congressman to have run statewide some day (gotta keep a good political bench!) if he proved himself in Congress. He told me he hadn't been involved in politics before (maybe not even voted????), but maybe some voters would find that refreshing. I just looked at him and tried to keep a straight face. "Oh, okay Jay." Spend a couple years workin' it in the GOP, let people get to know and trust you, let people see where you stand within the party, and maybe they'll be ready to trust you with a major elective office based on more than a hunch.
I've heard way too many stories about Foxx spinning a different tale depending on who she's talking to, especially on social issues, to trust her further than I could throw her. I'm sure she'd be a decent congresscritter, but take her newfound support for a Marriage Amendment for example. I'd bet that when push came to shove she'd team up with the House moderates against the conservatives to go for a very weak, hollow Marriage Amendment, one that allowed civil unions and goodness knows what else, and then come home and spin it that she worked to get the strongest M.A. possible.
