Incumbent Rod Blagojevich proven to be an incredible fundraiser, and governed a relatively strong blue state. But recent opinion polling showed that his approval rating at a rather dismal 44%. Blagojevich initially had the advantage in the general election, leading his Republican challenger, state Treasurer Judy Baar Topinka by eight percentage points in polls, although not reaching the fifty percent "safe zone" for incumbents. In March, Topinka won the GOP primary by 38% to 32% over dairy magnate Jim Oberweis. Meanwhile, a former Chicago Alderman named Edwin Eisendrath won a surprising 30% in the Democratic primary. During the election United States Attorney Patrick Fitzgerald was looking into the hiring practices of Governor Blagojevich.
