As Ronald Reagan might have said, prepositions are stupid things. And one of them got Sen. Scott Brown (R-MA) into a heap of trouble after he told local business leaders in Massachusetts last week that he would vote "for" the House-passed GOP budget when it hits the Senate floor.

After a week's worth of blowback, his staff now says he meant to say he will vote "on" that budget -- but he hasn't yet figured out how.
