Definition of hypocrites

What the hell is Joe Lieberman doing speaking at the Republican National Convention? Yes, he's an Independent, but he was the VP pick in the 2000 Democratic presidential ticket, ran for the 2004 Democratic presidential nomination, and he caucuses with Democrats. Someone explain this to me.

Also, I'm sure you've heard by now the talk about Republican VP nominee Sarah Palin's pregnant, teenage daughter. The Republicans are all upset that the "liberal" media is unfairly calling attention to it, attacking her, etc, etc. The line below from this Reuters article pointed out exactly for me why Repubs are so good at being hypocrites:

McCain spokeswoman Nicolle Wallace criticized "hateful" slurs and innuendoes in the liberal blogosphere. "I think the private life of a 17-year-old child ... is something that was being used as a political weapon by liberal bloggers and advocates of Democratic and liberal causes," she said on Tuesday on NBC's "Today" show.

Now you KNOW that if this had been Joe Biden's 17-year-old pregnant daughter, the right wingers would be all, TEH SIN, where are the PARENTS? HOW irresponsible! OMG, she is having TEH SEX. And would be calling him a bad parent for allowing his child to have sex. I cannot get over the fact that the Repubs are suddenly okay with a 17-year-old having the right to have sex in her private life and using the right to PRIVACY (reproductive rights argument, anyone?) as reason that the liberals are attacking unecessarily and should leave her and Palin alone.
