From James "The Ragin' Cajun" Carville (via a Drudge link):
"Gore will run again because, quoting George Will, running for president is like sex: "You don't do it once and forget about it."
Runner(s) up from Carville:
"Rudy Giuliani has been married more times than Mitt Romney's been hunting."
On HR Clinton and Obama: "Mama needs more spice, and Obama needs more seasoning."
