(Chicago, IL) -- It looks like U.S. Senator Dick Durbin may have a fight on his hands. A new poll reveals his GOP contender Jim Oberweis is closing the gap on him. "We Ask America" asked just over a-thousand people to who they'd be voting for in November. About 48-percent say they'll be backing Durbin while 41-percent say they're supporting Oberweis. Oberweis is a state senator who has spent much of his time campaigning in black communities on the south side of Chicago. Several high profile black pastors who usually vote Democrat say they need to see change in their communities, so they're backing Oberweis for Senate.
