watch cnn and ny1's democratic debate, moderated by wolf blitzer, thursday, april 14 at 9 p.m. et.









milwaukee (cnn) two candidates vying to take down their parties' front-runners could get big boosts if they win tuesday in wisconsin .









texas sen. ted cruz is leading donald trump in the badger state's polls. and a bernie sanders win would mark his sixth victory over hillary clinton in the last seven states to vote.









it's the last big test until april 19, and each candidate has a lot to win <u+2014> or lose.









here are five things to watch tuesday:









wisconsin is the first electoral test of whether he's paying a price.









but the polls show cruz with a 10-point lead in wisconsin -- and if that margin grows tuesday, it'd be a sign that the controversies swirling around trump's campaign are taking their toll.









still, trump was inflating expectations monday in la crosse.









"i really believe tomorrow were going to have a very, very big victory. very very big," he said. "you know, i've been up here a lot. and i love it, and the people i love."









"his team doesn't understand how these processes work so any time they lose they scream, 'the election's been stolen from us,'" cruz said monday on wisn radio in wisconsin. "it's just silliness."









a loss would dent trump. but it would crush cruz, who has retail politicked his way across the badger state as if it were iowa in recent weeks.









he'll try to pick up 42 more in wisconsin: 18 that go to the statewide winner, plus 24 more chosen three apiece by the state's eight congressional districts.









part of wisconsin's importance to cruz is that the calendar soon shifts to shakier ground for him. he's favored in the winner-take-all south dakota, montana and nebraska contests, but could lose big in the next contest on the calendar, new york on april 19, and then maryland, pennsylvania, connecticut, rhode island and delaware the following week.









"just a couple of weeks ago, all of the media commentators were saying wisconsin was a state that i could not compete and do well," cruz said monday in kenosha. "they were saying it was a state that was a natural state for donald trump. the state historically has been a purple or even a blue state at times. it's a state that is, that is very heavily based on manufacturing, that has a lot of union members and working class members. supposedly, it was donald trump's sweet spot, and yet i think the people of wisconsin, they're looking at the records of the candidates, and they realize that donald screams and yells a lot, but he has no solutions."









he was swept in the south, and bloodied in the rust belt. but when the race shifted west, bernie sanders won five out of six states, regaining his footing and bolstering his argument to take the race all the way through the last contests on june 7.









a win in wisconsin would give him a significant boost just as the race heads to new york -- the state where he was born, and which clinton represented in the senate. it would also give him victories in six out of the seven states in the month leading up to it -- helping to fuel the passion and small-dollar donations driving his candidacy.









at a rowdy monday evening rally in milwaukee, sanders talked repeatedly about "momentum" -- touting poll results, his growth from 2015 and a string of recent victories.









"tomorrow, if there is a good turnout here in wisconsin, if there is a record-breaking turnout here in wisconsin, we are going to win here as well," he said.









how problematic is a loss for clinton?









clinton's campaign has downplayed the wisconsin primary for weeks, arguing that the state's results won't tip the delegate count significantly in either direction. the former secretary of state wasn't even in wisconsin on monday -- instead campaigning in new york, where she faces a closer-than-expected contest in two weeks.









for more than a month, clinton has tried to shift her attention to republicans and the general election. yet much like clinton against then-sen. barack obama in 2008, sanders' persistent presence won't allow it.









clinton campaign manager robby mook is telling supporters not to worry.









in a memo posted on medium monday evening, mook wrote: "sanders has to win the four remaining delegate-rich primaries -- new york, pennsylvania, california, and new jersey -- with roughly 60% of the vote. to put that in perspective: sanders has thus far won only two primaries with that margin: vermont and new hampshire."









he calls the campaign's delegate lead "nearly insurmountable."









rubio, in fact, still has more delegates than kasich.









"he's just a stubborn guy," trump said of kasich. "he's stubborn. he doesn't want to leave."









wisconsin, just like michigan and illinois before it, is the sort of state where kasich ought to have a strong showing. public polls have showed him within striking distance of trump for second place -- and finishing ahead of trump would be a major boost.
