You knew it was a bad night when Donald Trump turned down the cameras. No gloating press conference. No stream-of-consciousness rant. In Wisconsin, Trump went down hard and he didn't want to front.
It capped a sensationally bad week. His campaign manager was charged in Florida with criminal battery, which The Don backed up on national TV by stating that women should be punished for having abortions.
It doesn't matter that he mightn't believe his own statement - the interview blunder exposed the danger of making up policy on the spot. Could this be it? Could this be the end? Is Trumpism fizzling out?
It's a brave pundit that strikes down The Don's chances this far through the race but it's an unusual phenomenon to see the leading campaign in the US primary race weakening by the day.
Forty-eight hours after being hammered in Wisconsin, Trump promoted his delegate manager to begin preparing for what might well be a contested convention in July.
