Like a pack of junkyard dogs snarling about distemper, Karl Rove group's new anti-Keystone XL attack ad rips Bruce Braley for being billionaire's tool

Karl Rove, the shameless maestro of political deception, is now running interference for Iowa U.S. Senate candidate Joni Ernst by attacking Keystone XL opponent Bruce Braley as a billionaire's tool. The attack-ad slush fund he started, American Crossroads, is organized as a 501 (C) (4) "social welfare" organization that doesn't have to disclose the identity of its GOP wealthy donors.

GOP politicians in the pocket of TransCanada lately have been comparing the proposed Keystone XL pipeline to Hoover Dam. Not even close, as the chart at left, prepared by ThinkProgress shows.
