Article Photos: For Romney, Obama, long slog to nail-biter finish 5/6

  FILE - In this Sept. 7, 2011, file photo, Republican presidential candidates, from left, Rep. Michele Bachmann, R-Minn., former Massachusetts Gov. Mitt Romney, and Texas Gov. Rick Perry, stand together before a Republican presidential candidate debate at the Reagan Library in Simi Valley, Calif. It's easy to forget there was a time when Bachmann was the surprise breakout from the GOP primary field. To be replaced by Texas Gov. Rick Perry. And then others. Romney pulled the plug on his first presidential run on Feb. 7, 2008, and immediately served notice that he wasn't about to fade away. "I hate to lose," he told conservatives that day.
