Arianna Huffington and Rudy Giuliani got into it this morning on MSNBC, with Joe Scarborough playing referee. Giuliani was on to talk about his endorsement of Marco Rubio for Senate in Florida. Huffington turned the conversation to Giuliani’s support of NYPD commissioner-turned-convicted felon Bernard Kerik.

Said Scarborough, “If we’re going to do this Arianna, understand we’re going to talk about your race in California. You ran for governor in California and it was a complete flop. But I still want to hear your ideas. And I don’t go back to your failures here or your failures there, but for some reason you’re doing it with Giuliani.”
