Romney, Obama go for laughs at charity gala
President Obama and Mitt Romney compete for votes. They try to outdo each other in fund-raising, and who can create the best television ad or deliver the most pointed one-liner in a debate. On Thursday, they competed for laughs. Appearing back-to-back at a gala in New York that raises money for charity, the candidates alternated between self-deprecating humor and edgy roast material.
