UPDATE: Ted Cruz has won the Republican presidential primary in Wisconsin. The win gives critics of Donald Trump hope that they can stop the GOP front-runner's rise to the party nomination. They are trying to deny him the majority of delegates and force a contested convention in July.
The Texas senator is casting his victory as a sign that he is the only candidate who can stop Trump. He's calling on Republicans to unify behind him and pushing Ohio Gov. John Kasich to drop out of the race.
Trump is the favorite in the next primary on April 19 in his home state of New York. He remains the only Republican who can clinch enough delegates to capture the nomination before the party convention.
Ted Cruz wins the Republican presidential primary in Wisconsin, a victory for the Texas senator over front-runner Donald Trump that slows the billionaire businessman's bid to win the GOP nomination outright.
