Chances Of A Contested Convention Jump After Ted Cruz's Big Win In Wisconsin

Donald Trump was having a rough week even before he got clobbered by Texas Sen. Ted Cruz in Wisconsin's primary on Tuesday. Prediction markets -- which allow people to bet on what they think will happen -- showed his chances of winning the nomination dropping over the last week. The chances of a contested Republican convention requiring two or more votes have climbed to 75 percent.

PredictWise, which estimates these probabilities based on those prediction markets, shows that the likelihood of a contested convention has grown 14 percent in just a week. The likelihood of Trump winning the nomination has dropped by 19 percent in the same amount of time.
