(CBS News) More than four in ten of the people who voted for Mitt Romney and Rick Santorum in Tuesday’s GOP primary in Illinois “have reservations” about their choice, according to early CBS News exit polls.CBS News

Early exit polls hint at a good night in Illinois for Mitt Romney.

Rick Santorum stepped in it this week, giving Romney a perfect in on the economy, which Santorum hasn’t pressed. He’s also leaning too far in on social issues. Why he isn’t pressing his grandson from a coal miner story I have no idea.

Let’s see how well Romney does with women tonight. Ann Romney has been working to warm up his image, but there’s a long way to go.

Pres. Obama leads Romney with women by 20 percentage points. He’s won them back since the 2010 midterms when the big two parties split the female vote.

UPDATE: Mitt Romney beat Rick Santorum soundly. Romney had some new talking points in his speech, which tilted general election, but he wasn’t on his game, stumbling quite a few times.

Santorum had his one-on-one chance against Romney and couldn’t get the job done. Rick Santorum spoke in front of a “freedom” banner, but also decided to pick up his economic populist theme, which is what he should have been doing all along. Santorum made his speech from Gettysburg, PA., where he said he expected a landslide “in five weeks.”

Newt Gingrich’s statement was unsurprisingly ungracious, whining about the money Romney’s campaign spent in Illinois.

Santorum’s going nowhere and if you couple that with Gingrich’s sour grapes, what you get is two opponents who don’t like the man who will be the nominee and are going to do their best to deny Mitt Romney 1144, so that negotiating is required for the nominee to be chosen.

First, there are reportedly “ballot problems” in 25 counties in Illinois.
