Larry Mantle is joined by NPR’s political team for a roundup of the week ahead on the campaign trail as candidates battle over Wisconsin’s primary.

Speaking in LaCrosse today, GOP candidate Donald Trump said a win in Wisconsin would effectively end the GOP presidential nominating fight and allow him to focus on defeating Democrat Hillary Clinton. He also called on Ohio Governor John Kasich to drop out - Kasich said that amounted to whining.

Senator Ted Cruz was on the hustings in Madison this morning and told reporters a win in the state would give him momentum moving forward.

As for the Democrats, Senator Bernie Sanders told Wisconsin voters he would rebuild the state's trade unions that were targeted by Republican Governor Scott Walker. Hillary Clinton is also campaigning on worker issues today, but she's in New York lauding that state leadership's plans to boost the minimum wage to $15 an hour.

What are you paying close attention to as these races continue?
