Actor and director Rob Reiner’s political activism goes further than money. He hit the campaign trail for both Al Gore and Howard Dean during their respective presidential bids, and, in 2009, co-founded the American Foundation for Equal Rights to overturn the passage of California’s Proposition 8 banning gay marriage. He was a Clintonite in ’08, but that didn’t stop him from cutting Obama’s presidential campaign a fat check after the primary was over, and quite a few more for the re-election campaign have followed.
