Kirsten Gillibrand seemed like one of the weaker incumbent senators going into the 2010 election cycle. She was appointed to the job by the now-disgraced Gov. Paterson. She’d only served little more than a single term in Congress when she was appointed. And she had some issue positions that worked for her upstate district but didn’t necessarily fit that well for running statewide in New York. But somehow over recent months numerous Republicans and Democrats have sounded out a run against her, only to decide against it — Ford, Zuckerman, Giuliani, McCarthy, Maloney, the list goes on and on. Is she an unstoppable force in politics? Evan McMorris-Santoro has the story.
