On Tuesday, the dislike that President Obama and Mitt Romney have for each other was palpable at the Hofstra University debate. Tomorrow night, they will be at the Al Smith Dinner, the annual charity gala for the New York Archdiocese. In the heat of the presidential campaign, it has become a tradition for the two major party candidates to address each other — in stand up humor. Just how biting Obama and Romney will get in their jokes depends on whether they go safe with self-deprecation or more daring with actual zingers. Here’s a sample of John McCain and Obama speaking at the dinner in 2008. The event is named in honor of the former New York governor who was the first Catholic on a major party ticket when he was the Democratic nominee for president in 1928.
