He'll be making his identity known today, and Huffington Post says he was motivated by Bill Clinton:
WASHINGTON — Bill Clinton won the presidential election for Barack Obama. But it wasn't his masterful Democratic National Convention speech or the advice he offered the president's reelection campaign. Clinton, it turns out, inspired the man who filmed Mitt Romney's infamous and game-changing 47 percent comments...
The man, who tended bar for a company that catered to a high-end clientele, had previously worked at a fundraiser at a home where Clinton spoke. After Clinton addressed guests, the man recalled, the former president came back to the kitchen and thanked the staff, the waiters, the bartenders, the busboys, and everyone else involved in putting the event together. He shook hands, took photos, signed autographs, and praised the meal — all characteristic of the former president.
When the bartender learned he would be working at Romney's fundraiser, his first thought was to bring his camera.
Meanwhile: How did Romney treat the bartender and the rest of the staff at the infamous event? Take a wild guess.
