Decision 2012: Mitt Romney wins the Illinois primary

Mitt Romney easily won the Republican presidential primary in Illinois by gaining 47 percent of the vote compared to 35 percent for his nearest rival Rick Santorum. So far, Romney has 563 delegates, according to an Associated Press count. That's nearly half the 1,144 delegates required to clinch the GOP nomination.

Class discussion: Romney won the support of three quarters of those Illinois Republicans who said their top goal is defeating President Barack Obama in the fall.
