RACHEL MADDOW: Why shouldn't I be asking you if you're running for president?
SEN. CLAIRE MCCASKILL (D-MO): You know. What an awkward awful question.
MADDOW: If I were you I would be running.Why aren't you running?
MCCASKILL: I don't know, sometimes me stepping in is kind of like a bull in a china shop
MADDOW: We're not a china shop, we're America!
MCCASKILL: I'm passionate and I'm not afraid to take a fight where I think it needs to be taken. But I also know what the process is, and besides that, I'm all in for the first woman president Hillary Rodham Clinton, so I want to be supporting her in any way I know how.
