The2012 United States presidential election in Illinois took place on November 6, 2012, as part of the2012 United States presidential election in which all 50 states plus theDistrict of Columbia participated.Illinois voters chose 20 electors to represent them in theElectoral College via a popular vote pittingincumbentDemocraticPresidentBarack Obama and his running mate,Vice PresidentJoe Biden, againstRepublican challenger and formerMassachusetts GovernorMitt Romney and his running mate,CongressmanPaul Ryan. The Obama/Biden ticket won Illinois with 57.60% of the popular vote to Romney/Ryan's 40.73%, thus winning the state's twenty electoral votes by a margin of 16.87%.[1]
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 16.87% 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 carryingGallatin orMacoupin counties, as well as the first sinceWoodrow Wilson in1916 to win the White House without carryingMadison County.
As of the2024 election, this is the last time that a Democrat carriedAlexander,Carroll,Fulton,Henderson,Henry,Jo Daviess,Knox,Mercer,Putnam,Warren, andWhiteside counties. It is also the last time a Democrat won more than 15 counties in the state.

While Obama only won 23% of the counties in Illinois, most of the counties he won were heavily populated. His 17-point victory is attributed to his landslide performance inCook County where he received 73.88% of the vote and victories in the once Republican-favored collar counties (DuPage,Will andLake). He also performed well in theEast St. Louis area. Cook County, which encompasses theChicago Metropolitan Area, provides a crucial advantage for the Democratic Party. If Cook County's vote were excluded, Romney would have won the state with 1,639,684 to Obama's 1,530,975.
As of the2024 presidential election, this is the last time a Democrat has wonAlexander,Carroll,Fulton,Henderson,Henry,Jo Daviess,Knox,Mercer,Putnam,Warren andWhiteside counties. Also, as a result of this election,Clark,Clay,Effingham,Edwards,Iroquois,Jasper,Massac,Richland,Wabash andWayne are the only counties in the state that never voted for Obama in his two runs for the presidency or in hislandslide election to the Senate.
