The Chicago Tribune has endorsed Mitt Romney:
For his demonstrated abilities and the economic pragmatism at his core, the Tribune endorses former Gov. Mitt Romney of Massachusetts as the Republicans' best, most responsible choice in Tuesday's Illinois primary. The other three contestants, for lack of Romney's credibility on this threat to the American way, can only try to talk a good game. We're far more confident that Romney is the candidate best equipped to keep the U.S. from devolving into New Europe.
