Illinois was in the spotlight Friday, with Romney, Santorum and the man they hope to get the chance to challenge all appearing in the state.
In the GOP race here, it's all but down to two men, with recent polls in Illinois showing Romney leading Santorum by a small margin.
Former House Speaker Newt Gingrich, badly damaged after losses in Alabama and Mississippi on Tuesday, campaigned in the Chicago area this week. But the former Georgia congressman was in Louisiana on Friday. Longshot Texas Rep. Ron Paul has campaigned little in Illinois, though he headlined a rally at the University of Illinois on Wednesday. Neither contender was advertising in the state.
In contrast, Romney and his allies are dominating Illinois' expensive TV airwaves. His campaign was airing about $1 million in TV ads this week, and a political action committee that supports him was spending $2.4 million on an ad aimed at undermining Santorum's appeal as a conservative. The ad notes Santorum's past support for earmark spending, raising the debt limit and allowing felons to obtain the right to vote.
Looking ahead in the upper Midwest, the pro-Romney group, Restore Our Future, also has begun airing ads criticizing Santorum in Wisconsin.
In Illinois, Santorum and a group that supports him — Winning Our Future — were spending only about one-fifth of the pro-Romney advertising. The pro-Santorum group was on the air in Louisiana, looking to counter an onslaught of negative ads by the pro-Romney group.
Romney's message is focused squarely on the economy in Illinois, where unemployment was 9.3 percent in February, the eighth-highest in the country.
"Romney will do well in the Chicago suburbs. Santorum will do well deep downstate," said Dan Curry, a Republican strategist and veteran of several statewide campaigns. "Illinois has its own unique nature that really matches the country."
While Chicago dominates Illinois politics, the Republican primary electorate is divided evenly between the GOP-heavy suburbs and the rural and southern reaches outside the metro area.
Santorum, who won primaries in Alabama and Mississippi on Tuesday, is banking on his appeal to rural conservatives, including the evangelical base in central and southern Illinois. Santorum, who also won the Tennessee primary on March 6, will include on his statewide tour Saturday a stop in Herrin, Ill., a town 100-miles closer to Memphis than it is to Chicago.
The 54 delegates at stake Tuesday are directly elected by voters, while 15 more will be named at the state party convention in June.
Romney has been the most aggressive cultivating the state, although the last time he set foot in the state was November when he held a fundraiser.
He has lined up Republican establishment figures. Sen. Mark Kirk, state Treasurer Dan Rutherford, Rep. Aaron Schock and state GOP chairman Pat Brady have endorsed Romney. The familiar names, who are on the ballot as Romney delegates, give Romney an edge in an election where voters actually select delegates.
Romney, who has flexed his campaign organization to narrow victories in Michigan and Ohio, has fielded a full slate of delegates in all 18 of Illinois' congressional districts.
Santorum has struggled to organize and was unable to field delegates in four Illinois districts, where a total of 10 delegates are at stake Tuesday.
