Since somebody quoted the comment, I can see that the facts still don't enter into anything to do with Palin, or her supporters. The joke was about her 18 year old daughter, who was an unwed pregnant girl who had just gotten knocked up in the past year. See, that's what makes it a joke, the fact that she did get knocked up, and of course had had sex, and A-Rod is someone who has sex with women, in New York.
A joke about her 14 year old daughter wouldn't be funny to Dave, or to anyone, really. To think that's what the joke was about just shows a lack of a sense of humor, among other things... but we're familiar with that by now.
