It all depends on who the debate moderators are, and the questions they ask. Don't forget, the GOP has a long history of agreeing to squishy, leftist moderators.
Ted Cruz won’t make the mistake both Bushes & Romney made (`moderators are fair & balanced’). He knows the long knives will be out & he’ll come prepared.
George Snufflelopagus or Candyface Crowley won’t get to play their sneaky tricks this time.
