Morgan Freeman has made a $1 million contribution to the pro-Obama SuperPAC Priorities USA Action in the type of high-profile donation supporters hope will lead to other giving if Democrats have hopes of achieving any kind of parity with the flood of money going to outside groups backing Republicans.Freeman’s donation, made in June, will be included in the org’s report to the Federal Election Commission filed Friday. In a statement issued by Priorities, Freeman said, “Priorities USA is doing a great job of protecting the values I believe in. I am happy to help them, and I hope others will do so as well.” The SuperPAC was launched last year by former White House aides Bill Burton and Sean Sweeney and drew initial support from Jeffrey Katzenberg, who gave $2 million and, along with his political adviser Andy Spahn, has been helping them raise money within the entertainment community. But Democratic-oriented SuperPACs have had trouble matching the contributions going to Republican-aligned groups, in part because of opposition on the left to the Supreme Court’s Citizens United decision and the perception that it has led to a flood of big money from individual donors into politics. But other donors who have decried Citizens United say it doesn’t make sense to watch the other side create an uneven playing field, particularly when it comes to the fall campaign.
