"I favor legalizing same-sex marriages, and would fight efforts to prohibit such marriages," - Barack Obama, to the Windy City Times in Chicago, in 1996.
Some context from the emailed press release:
During the final weeks of the presidential campaign last fall, several media outlets contacted Windy City Times because of an old internet story from the 1996 Illinois state Senate race. In that campaign, Outlines newspaper reported that 13th District candidate Barack Obama supported gay marriage. Reporters wanted to know what exactly Obama had said. Outlines summarized the results in that 1996 article by Trudy Ring, but did not list exact answers to questions. In that article Outlines did note that Obama was a supporter of same-sex marriage and that article was never challenged or corrected by Obama. Just recently, the original Outlines and IMPACT surveys were found in the newspaper's archives.
