that Romney telling a heckler:
If you’re looking for free stuff you don’t have to pay for, vote for the other guy. That’s what he’s all about, okay? That’s not, that’s not what I’m about.
was among his best moments as a candidate yet.
It implies a whole set of questions and concerns and answers them: What is the proper role of government? Who is this candidate? Are the promises of the last almost four years sustainable? Even workable?
It was, obviously, only a moment, and does not answer all questions or address all concerns, but it was an effective response from Romney.
