The only committed conservatives I see mentioned ever are Pence and Tancredo.Name ID will rise with time.
Tancredo has name recognition. His silly statement about nuking Mecca has doomed any presidential ambitions, ever.
And Mike Pence has no platform from which to gain name recognition. He is not a "go to" guy when the press wants a comment on something, or for the Sunday shows.
So who's ever going to hear about him?
