What's at Stake in the Race for Wisconsin's Delegates

Wisconsin's primary could be a turning point in the cycle.

Here’s a rundown of everything at stake today.

GOP

State voting: Wisconsin

Delegates up for grabs: 42

Delegate Allocation explained: Of the 42 delegates, 24 are in Congressional districts, (3 in each of the 8 districts) and 18 are at-large delegates. The at-large delegates are winner-take-all and based on the statewide vote. Whoever wins the statewide vote gets all 18 delegates. The Congressional districts are winner-take-all based on district. So, for example, if Ted Cruz wins one Congressional district, he will get all 3 of the delegates there. If he wins all 8 districts, he will get all 24 delegates.

However, Trump does have one advantage: Wisconsin is an open primary, where he tends to perform better than in caucuses and closed primaries.

State voting: Wisconsin

Why it matters: Sanders has proven he can play in the Midwest, beating Clinton in Michigan and coming in close behind her in Missouri and Illinois. According to a recent Marquette University Law School poll, he has a four point lead over her. Clinton leads Sanders by 263 pledged delegates, and her lead widens to 701 delegates when incorporating the superdelegates who have committed to her. Even if Clinton loses in Wisconsin, Sanders is unlikely to make a dent in that delegate lead; If the race is as close as the polls are forecasting, the Vermont senator is unlikely to gain many more delegates. And while Clinton needs to win 42 percent of the remaining pledged delegates, Sanders needs to win 57 percent. When factoring in superdelegates, Clinton need to win 36 percent and Sanders needs to win 73 percent.

But while math may be on her side, a loss in Wisconsin would mean Clinton heads into her adopted home state of New York having lost six states in two weeks -- a fact Sanders is well aware of.
