Thursday witnessed major developments in the 2012 presidential campaign. Texas Gov. Rick Perry suspended his campaign and endorsed Newt Gingrich. John Gizzi of Human Events explains whet went wrong with the Perry campaign after a meteoric start and assesses how much of an impact the Perry endorsement might have on Gingrich’s fortunes. Gizzi also reacts to an ABC News interview in which Gingrich’s second wife alleges the former Speaker of the House wanted an ‘open marriage’ so he could carry on an affair with the woman who is now his third wife. Gizzi explains why the sordid tale could cut both ways on the campaign trail. He also tells us why the Jon Huntsman campaign never managed to get off the ground.
