Obama's victory continued a Democratic winning streak in the state — with the Democratic candidate having carried Illinois through six consecutive elections. However, despite Obama's win in 2008 and popularity in the state due to being its former U.S. Senator, his performance significantly worsened, with his margin of victory decreasing from 25.10% to 16.84% and losing 23 counties to Romney that he had won four years prior. Obama further became the first ever Democrat to win the White House without carrying Gallatin or Macoupin Counties, as well as the first since Woodrow Wilson in 1916 to win the White House without carrying Madison County. While Obama only won 23% of the counties in Illinois, most of the counties he won were heavily populated. His 17-point victory can be largely attributed to his performance in Cook County, which encompasses the Chicago Metropolitan Area. He also won the once Republican-favored collar counties (DuPage, Will and Lake). He also performed well in the East St. Louis area.
