(Green Bay, WI)-- In Wisconsin, voters will head to the polls in less than four weeks to pick a Republican presidential nominee.
The Republican presidential candidates have yet to make campaign stops or buy any advertisement air time, but all that could change because of Super Tuesday's results.
Political Scientist David Littig said he's never seen a Republican primary quite like this one. He says, despite Mitt Romney winning six out of ten elections Tuesday, that there is no clear front runner.
"It really shows a deep, deep divide within the Republican party that they have rarely had, and in other words it's not going to be decided when it comes to Wisconsin," said Littig, "You have the pragmatic corporate urban Republicans supporting Romney, socially conservative rural, blue collar Republicans supporting Rick Santorum, so it's totally split this way."
Wisconsin has 42 delegates at stake on April 3, that's out of the 1,144 needed to win the nomination.
As of today, Mitt Romney has the most delegates with 404. Rick Santorum has 165, Newt Gingrich has 106 and Ron Paul has 66 delegates.
Littig predicts Wisconsin will follow suit with its neighbors to the left and south choosing Rick Santorum as the Republican candidate.
"I would not be a bit surprised if Santorum carried Wisconsin," said Littig.
Littig also said expect the national spotlight on Wisconsin on April 3. The only other primaries that day are in Maryland, and Washington D.C.
None of the candidates have bought air time in the state. Local Five's national campaign salesman says the candidates and Super Pacs are not buying ad time until a few weeks ahead of time, which is typical in a presidential primary. And when the ads are finally out, he said you can expect to see more Romney ads than ads for anyone else, as he's been the biggest spender of the four.
