Illinois District 5 did have a Republican (Mike Flanagan) from 1995 to 1997, who unseated 18-term incumbent Dan Rostenkowski with 54% of the vote. However, he was probably target numero uno by Dems in the 1996 election, having been narrowly elected in a staunchly Dem district. He was soundly defeated by Blago in that election, only getting 36% of the vote.
Then Patty has a chance.
