Illinois Primary Results 2012: Live Updates

The Illinois primary results have all eyes on the Land of Lincoln on Tuesday night.

Former Massachusetts Gov. Mitt Romney was favored over rival candidates former U.S. Senator Rick Santorum, former House Speaker Newt Gingrich and U.S. Rep. Ron Paul going into the contest.

HuffPost's Jon Ward reports:

Santorum didn't do better than polls had projected him to do that night in Ohio two weeks ago, and lost. But he shocked the political world one week ago by winning Mississippi and Alabama, despite polls indicating he was most likely to come in second or third in both states.

The insurgent presidential candidate and his supporters are pulling for another surprise on Tuesday in Illinois, where two polls Monday showed frontrunner Mitt Romney with a double-digit lead.
