This is from NewsBusters, via Doug Powers at Michelle Malkin's blog.
Doug Powers helpfully points out that the BS Removal Kit can also be used to remove the "McCain" half of your McCain/Palin bumper sticker.
I don't have any bumper stickers to remove, but I'm always happy to help a friend find something useful.
Then again, you might just want to keep those stickers on for posterity. I used to commute long distances to work and would frequently see another commuter with a really old Dodge Dart that had a Nixon/Agnew sticker on his car. Together, the sticker and car made a nice time capsule of another era. Something to consider before you plunge headlong into the BS Removal decision...
