My list w/reasons:
Fred Thompson—strongest federalist, strong on immigration, WOT, Social Security
JC Watts—true conservative & antidote to Obamanism
Duncan Hunter—Strong on immigration, WOT
Steve King—look him up, you’ll be impressed, Midwestern
Jim DeMint—VERY conservative!
Haley Barbour—Hero of Katrina, competent, executive experience, ran RNC, good lever puller
General David Petraeus—OBVIOUS
Steve Forbes—Economic knowledge w/o Mitt’s baggage, Flat Tax
Sheriff Joe Arpaio—strongest anti-illegal official in USA
Bobby Jindal—10 years executive experience, still young, “next Ronald Reagan” says Rush.
I would add Micheal Steele, another good conservitive.
