Crossroads GPS and its sister super PAC, American Crossroads, were co-founded by Republican strategist Karl Rove in 2010, shortly after a series of federal court decisions opened the door to unlimited political spending by corporations and deep-pocketed individuals.
Together, the two groups brought in $325 million during the most recent two-year election cycle.
Another major conservative advocacy group, Americans for Prosperity, which has been supported by the billionaire industrialists Charles and David Koch, raised more than $190 million together with its related foundation in the 2012 cycle, as previously reported. (AFP spent $122 million of that last year alone, according to new documents filed in Colorado, first reported by the Center for Public Integrity.)
That means that donors coughed up more than half a billion dollars just for the Crossroads and AFP outfits, only to see Obama reelected.
