Until last week, Scott Prouty¡¯s only bout with fame came when he dived into a canal in Florida and saved a woman from drowning. Like many Americans, the Boston area native held down working-class jobs, ran into some financial trouble and remained generally anonymous.

But not many Americans are responsible for nearly bringing down a presidential campaign. And Prouty, 38, has now outed himself as the man who shot the infamous ¡°47 percent¡± video showing Mitt Romney dismissing President Barack Obama¡¯s supporters during a private fundraiser, the single event that more than anything else may have ruined Romney¡¯s shot at the presidency.

¡°I was behind this whole thing,¡± Prouty, who now lives in Florida, said as he revealed on MSNBC¡¯s ¡°The Ed Show¡± on Wednesday night that he had secretly filmed Romney¡¯s comments while tending bar at the $50,000-per-plate event.
