When the Republican establishment made clear that they would not support him for reelection, Fitzgerald announced he would retire at the end of his current term. Republicans nominated businessman Jack Ryan for the seat in the primaries. However, Ryan was later pressured by the Illinois Republican Party to withdraw because of publicity received from the contents of his previously-sealed divorce case. Fitzgerald stood by Ryan and supported him, despite the pressure from the media and the Illinois Republican party on Ryan to withdraw. Just 86 days before the election, the party drafted Maryland native Alan Keyes as the nominee. Keyes was accused of "carpetbagging," and was defeated by Barack Obama by more than 40 percent of the vote. It has been stated that Fitzgerald, who was popular among independents, stood the best chance of retaining the seat and defeating Obama, who went on to win the presidential election just four years later. During his final months in office, Fox News ran an op-ed on Fitzgerald, "Retiring Senator Stood Up for Principles."
