"Though I am not sure Thomspon has the experience to be POTUS."
Senators have been elected president. People who have only been elected to the office of mayor have not.
Rudy has the advantage of being seen by many as AMERICA'S Mayor, as opposed to being "just" a mayor of a city. 9-11 "nationalized" him.
Giuliani ran the largest city in the United States, with a police force larger than many militaries, and has an executive track record. He had more on his plate than many governors, and they get elected all the time. It's not like he was the mayor of Bokipse, Minnesota.
Fred Thompson is right on the issues, but very light on experience. Senators do get elected President, but his term was both short and unremarkable. He's a nice guy with a little political experience and a modest acting career. Reagan was govenor of California, and president of the Screen Actors Guild. That's executive experience, and quantifiable leadership. Thompson simply doesn't have that under his belt.
