I'm not sure how serving on a committe qualifies you for anything more than serving on another committee.
The American people typically look for someone who has a proven record of success in an executive position. That's the reason why only two sitting senators have ever been elected to the Presidency.
And only one member of the House was. He was the majority leader and also senator-elect at the time as well as a successful Civil War general.
I mostly like Hunter, but you're kidding yourself if you think his candidacy is going anywhere.
Duncan Hunter knows a heck of a lot more about the inner workings of the military and the Pentagon than Giuliani does. There is no doubt about that.
