In 2010, we learned from Martha Coakley that a candidate for statewide office in Massachusetts can't swing and miss on knowing their Boston Red Sox.
But there's another rule in American politics: tread carefully when you're (likely) running against a female candidate.
In an interview on WZLX radio this morning, Massachusetts Sen. Scott Brown (R) was asked about Elizabeth Warren's (D) answer to a debate question about how she paid for law school (when Brown paid for it, in part, by posing nude).
"I kept my clothes on" was Warren's retort at the Democratic debate.
And here was Brown's reply in his radio interview: "Thank God." That response produced laughs from Brown and the radio hosts. (The audio is here.)
