Alyssa watched Obama's Letterman appearance:
The line that’s getting a lot of attention is Obama’s reminder that the president represents everyone, a line he had to deliver that’s the obvious rejoinder to Mitt Romney’s nasty, condescending remarks about ignoring the 47 percent of people who will never vote for him. And that’s a line that Obama probably had to deliver. But I think the real power of this appearance is that it reveals how that video gives Obama the tool he needs to connect all the themes of his campaign, and to draw a final, and perhaps deadly, comparison with Mitt Romney.
The president, however, is catching some grief for another line: "I don’t remember what the number [of the national debt] was precisely."
