When Freedom's Watch ran an ad accusing Rep. Nick Lampson (D-TX) of "politics as usual," the group's line of attack was anything but usual.

Unlike a barrage of ads from independent advocacy groups attacking Republicans for accepting contributions from "Big Oil," Freedom's Watch accuses Lampson of taking donations from an environmentalist group — or rather, "a liberal special interest group that favors high gas prices." The group at issue was the Sierra Club. The ad ran over the last two weeks.
