Early voting tallies show U.S. Rep. Jesse Jackson Jr. with 75 percent of the vote in the Second Congressional District.
Jackson is under federal scrutiny for activity involving his campaign account. Since the Chicago Sun-Times first reported Jackson's mounting troubles Jackson returned to the Mayo Clinic for treatment.
Jackson has been absent from his congressional post since June 10 and essentially MIA on the campaign trail.
Initially, aides said Jackson was hospitalized because of "exhaustion." He was eventually transferred to the Mayo Clinic, where his family said he was being treated for bipolar depression. He returned to his Washington home in September and was seen drinking at a bar with different women. He did not return to his congressional job before returning to Mayo Clinic.
Jackson's challengers are virtually unknown rivals: independent Marcus Lewis; Republican Brian Woodworth, and write-in candidate Anthony W. Williams.
