Buttigieg's unlikely Iowa rise now carries high expectations

Pete Buttigieg finds himself in a place that he could hardly have contemplated when he began running for president a year ago: He likely cannot finish lower than second in the Iowa caucuses if he wants to advance in the Democratic presidential nominating campaign. “I’m not sure a win is necessary, but he’s got to be in the top two, I would think, to have any chance of moving on,” said Joe Trippi, campaign manager for former Vermont Gov. Howard Dean's 2004 presidential campaign. Each of the top four candidates in Iowa faces his or her own version of the challenge.
