Debate Subtext Primer

Potential Romney "zingers" in tonight's debate:

1. Teleprompter jokes.
2. Birth certificate jokes.
3. School transcript jokes.
4. Teleprompter jokes (because those never get old).
5. "Dependency President" jokes.

In a nut, each is a thinly-veiled racist attack, predicated on the white Republican base voters' fear of a black president.
