U.S. Senate Career
Encouraged by poll numbers, Obama decided to run for the U.S. Senate open seat vacated by Republican Peter Fitzgerald. In the 2004 Democratic primary, he defeated multimillionaire businessman Blair Hull and Illinois Comptroller Daniel Hynes with 52 percent of the vote. That summer, he was invited to deliver the keynote speech in support of John Kerry at the 2004 Democratic National Convention in Boston. Obama emphasized the importance of unity and made veiled jabs at the Bush administration and the diversionary use of wedge issues.
