resident Obama got some grief this week when he reversed course on super PACs, suddenly encouraging wealthy supporters to contribute to the political spending behemoths that can accept unlimited donations from individuals and organizations. (Read a quick primer on super PACs here.) Obama campaign manager Jim Messina explained the change of heart as a nod to reality, saying Democrats can't "unilaterally disarm" while cash pours into Republican coffers. How much cash? A lot, say Kenneth Vogel and Abby Phillip at Politico. A new report from two public-interest groups confirms fears "that the cash for big-ticket campaign spending like TV advertising is increasingly controlled by an elite class of super-rich patrons not afraid to plunk down a million bucks or more for favored candidates and causes." Here, a stats-based look at the "disturbing" super PACs:
