GOP front runner Mitt Romney is expected to take Illinois handily.
Recent polling suggest the former Massachusetts governor will grab the popular vote out of the Land of Lincoln's primary.
An average of recent polling, collected by Real Clear Politics, says Romney will win with about 37% of the vote. Romney get's the most love from Rasmussen Reports, which released its poll on March 15, predicts 41%.
Santorum comes in second and averages 31% of the vote, according to RCP. But Santorum is at a delegate disadvantage in Illinois because he isn't registerd in four of the 18 districts that make up Illinois.
Romney and Santorum were in Illinois Friday, and planned events for early next week, too.
According to the poll aggregate, Newt Gingrich will draw about 13% of the vote and Ron Paul will nab 7.3% from Illinois.
