We find the claim to be true. Yes, Obama worked with Republican members on some of the thorniest facing the Illinois General Assemby--even when it meant making his Democratic colleagues mad.
The legislature had not overhauled state ethics and finance laws for 25 years. Obama worked with a bipartisan group of four legislators, including Dillard, convened by former U.S. Sen. Paul Simon and the Public Policy Institute at Southern Illinois University.
"Obama worked very well with the other members of the group," said Mike Lawrence, executive director of what is now known as the Paul Simon Public Policy Center. Lawrence said that Obama favored more sweeping reforms than Republicans and others did, but was willing to compromise. The work resulted in the Gift Ban Act of 1988.
Obama worked with other Republicans on such issues as health insurance for kids and the state's death penalty--not an issue normally associated with bipartisan work between a liberal Democrat and Republicans.
Viewers may have watched the ad and decided Dillard was supporting Obama for president. But Dillard made the ad, despite saying that as a loyal Republican, he has endorsed Sen. John McCain for his party's presidential nomination--a fact that he did not mention in the ad.
