What exactly are you waiting for, Pete? The time to blockade and protest was two days ago.....
Conservatives blockading theaters would play right into Moore's hands. He'd love it. It'd just boost the controversy of the film, and he'd say conservatives try to supress free speech.
No, the best thing to do is to make voters aware of Moore's extremism and tie it around the necks of the Dems who have embraced him. Put up a TV ad, in South Dakota, for example, listing Moore's vicious anti-American quotes and then ask why Tom Daschle embraces and applauds this man, even to the point of delaying a vote on the defense budget to attend a screening of the film.

Blockade, shmockade. Stand in front of the theatre in full Muslim regalia. Ladies, take out your burkas. Go to the box office and ask for a thick with a Middle Eastern accent. Let out couple of impromtu "death to Israel and death to America". Watch the liberals/Dems in the audience. They won't know whether to crap themselves or go sailing.
