People for the American Way have launched their new anti-Alito ad, Fool Me Once. You can watch it online. From the text:

President Bush is trying to fool Americans into thinking that Sam Alito is a mainstream judicial nominee, which is why PFAW is committed to exposing the truth about Alito’s record and his judicial philosophy. This ad recounts troubling Alito rulings and legal positions, including his voting to uphold a strip search of a 10-year old girl without a valid warrant, his unsuccessful effort as an appeals court judge to declare a law regulating machine guns unconstitutional, and his declaration while in the Justice Department that the Constitution does not protect a woman’s right to choose an abortion.

Here are the reasons PFAW opposes Alito. And here's a handy guide where you can read about Judge Alito's decisions, with free links to the opinions themselves.

Fox News is refusing to air the ad.
