SCHAUMBURG, ILL. - Mitt Romney sailed past Rick Santorum to an easy victory in the Illinois primary Tuesday night, picking up his third big-state win in a row and padding his formidable lead in the race for convention delegates.
"What a night," Romney told cheering supporters in suburban Chicago. Turning his attention beyond his GOP rivals, he said he had a simple message for President Obama, the Democrat he hopes to face and defeat in November: "Enough. We've had enough."
Returns from 98 percent of Illinois' precincts showed Romney with 47 percent of the vote compared to 35 percent for Santorum, 9 percent for Ron Paul and 8 percent for Newt Gingrich.
That was a far more substantial showing for Romney than his grudging victories in the past month in Michigan and Ohio, primaries that had raised questions about the candidate's ability to rally the party behind him.
Santorum sounded like anything but a defeated contender as he spoke to supporters in Gettysburg, Pa. He said he had outpolled Romney in downstate Illinois and the areas "that conservatives and Republicans populate. We're very happy about that and we're happy about the delegates we're going to get, too."
"Saddle up, like [Ronald] Reagan did in the cowboy movies," he urged his backers.
Surveys of Illinois Republicans leaving the polls showed that Romney not only won among the groups that usually support him -- moderates, college graduates and wealthier voters -- but also was competitive among Santorum's generally more loyal coalition of Tea Party supporters and married women. If there was one driving force for Romney, it was the desire of Illinois Republicans to defeat Obama in the general election. Romney was supported by nearly three-quarters of those who said in exit polls that winning in November was their top priority.
