-- Wisconsin is a crucial primary state and the respective front-runners in the Democratic and Republican races are looking at a potential loss.
Here are the story lines to watch today as voters in the Badger State head to the polls:
1. Could Cruz Crash Trump’s Party?
A Marquette University poll released March 30 shows the Texas senator with a 10-point lead on Trump.
2. Close Race for the Democrats
Sanders recognizes the potential momentum he could get from a win in Wisconsin.
3. New Voter ID Requirement at Play
Wisconsin voters are required to bring a government-issued photo ID with them to the voting booths.
Since being signed into law in 2011, the voter-ID requirement has been a bone of contention.
While some argue the law prevents voter fraud, others see it as a way to block voters of a certain demographic.
Over 300,000 registered voters, mostly minorities or people below the poverty line, could be prevented from casting ballots, according to PBS.
4. Cutting Out Kasich
"We’re very excited about heading to New York," the Ohio governor said on “This Week” Sunday. "We're virtually tied with Donald Trump in Pennsylvania. We're starting to get to more home turf for me."
5. Republicans Duke It Out for Delegates
A portion of the delegates are awarded to the winner of the statewide vote, so, if that is Cruz, he adds 18 of the 42 delegates to his count. The remaining 24 delegates are split among the winners of each congressional district. In order to take home a large portion of delegates, the GOP candidate needs to win a majority of the state’s eight congressional districts.
How these delegates are allocated to the Republican candidates could set the path to a contested GOP convention.
