Republican presidential candidates will be heading into Illinois ahead of next week's primary... but so far, none of the candidates are scheduled to stop in Springfield. Frontrunner Mitt Romney isn't scheduled to arrive in the state until Monday, one day ahead of the voting, but that schedule could change. Newt Gingrich will focus primarily on the Chicago area and suburbs, while Rick Santorum plans stops in northern and southern Illinois. Ron Paul will visit the University of Illinois campus on Wednesday.
