Cable-news channels often provide soft landings for former or wanna-be elected officials, typically featuring them as political analysts. But just a few contributors have left a station to seek elected office, only to return to that same outlet after striking out. Pat Buchanan marched away from, and then retreated to, CNN'S Crossfire not once but twice, when he ran for president in 1992 and 1996. More recently, Fox News has rehired a handful of former contributors after voters rejected them. Here, Uherti presents more of them, including Angelea Mcglowan and Pete Snyder.
