Dim Bulb: Sen. Claire McCaskill, D-Mo.

WHAT: McCaskill disparaged House Speaker John Boehner and House Republicans on MSNBC’s “Morning Joe.” “I don’t know what he’s got going on in his caucus,” she said. “It looks like a hot, sloppy mess.” WHY IT’S DIM: A senator who is in hot water over whether she took advantage of that corporate jet deduction President Obama wants to abolish probably shouldn’t talk about other people’s hot, sloppy messes.

CURE: Release those tax returns.
