NEW YORK — Republican Donald Trump emerged from Wisconsin as a damaged front-runner following a crushing loss to rival Ted Cruz, deepening questions about the billionaire businessman’s presidential qualifications and pushing the GOP toward a rare contested convention fight.

Democrat Bernie Sanders also scored a sweeping victory in Wisconsin’s primary that gives him a fresh incentive to keep challenging Hillary Clinton. But Sanders still lags Clinton significantly in the delegate count.

Both parties are turning their sights toward New York, which offers a massive delegate prize in its April 19 contests. It marks a homecoming of sorts for several candidates, with Trump, Clinton and Sanders all touting roots in the state.
