FILE - In this May 9, 2007 file photo, then-Maryland Gov. Martin O'Malley endorses Democratic New York Sen. Hillary Rodham Clinton's campaign for the 2008 presidency at City Dock in Annapolis, Md. More than a decade ago, Bill Clinton spotted a political star on the horizon, someone he predicted would go from a big-city mayor to a national leader _ maybe even to the White House. In the years that followed, Clinton and his wife, New York Senator Hillary Rodham Clinton, showed up time and again as their young ally rose up the political ranks, hosting fundraisers, headlining rallies, and connecting him with their sprawling network of political donors.
