Tancredo, Hunter, and Thompson are the conservative rebellion. They will speak plainly, and they will push this election to where it needs to go.
My preference is Hunter, and I like Thompson. I like Tancredo, too, but I haven't heard him articulate a position on the offensive war, and for me the war is bottom line. I agree with others, that you can't separate border security from the war itself, but so far Tancredo hasn't shown much interest in war issues. That will probably change now, as he enters the race.
I am expecting him to be more isolationist than the others, more inclined perhaps to bring the boys home and focus on simply keeping the baddies out. I don't think that will be effective, I don't think we have that choice, personally, but I'll wait to hear Tancredo explain his own position.
The GOP Presidential debates should be pretty decent and very telling about all of the candidates on all of the issues and personal lives.
