Obama has a zinger. Asked about whether or not he has authenticity as a black man, he says he proves his credentials when he tries to catch a cab in Manhattan.
Hillary has a good one on whether or not her femininity is in question: "I can't run as anything but a woman." Now Edwards is taking on the question of women — more women than men have trouble getting the health care they need, more women are affected by the minimum wage, and so on. He commends Senator Clinton for her lifetime of work on behalf of women, but claims he is the best advocate for them.
A couple totally awesome questions on gay rights. A lesbian couple asking if the candidates would allow them to marry if they were elected, and then a Baptist pastor who said, if religion was used to justify slavery, banning interracial marriage, and other injustices, and we recognized that was wrong, how can we use religion to deny gay Americans the right to vote. This is the sort of stuff conventional moderators would not have brought up. At least one cheer for YouTube, and Politics 2.0!
