2012 United States presidential election in Indiana

The 2012 United States presidential election in Indiana took place on November 6, 2012, as part of the 2012 United States presidential election, in which all 50 states plus the District of Columbia participated. Indiana voters chose 11 electors to represent them in the Electoral College via a popular vote pitting incumbent Democratic President Barack Obama and his running mate, Vice President Joe Biden, against Republican challenger and former Governor of Massachusetts Mitt Romney and his running mate, Wisconsin Congressman Paul Ryan. Romney and Ryan carried Indiana with 54.13% of the popular vote to the Democratic ticket's 43.93%, thus winning the state's 11 electoral votes.

Indiana and North Carolina were the only two states Obama won in 2008 that flipped to the Republican column in 2012. Although Indiana normally leans Republican, in 2008 Obama had been the first Democrat to win Indiana since 1964, albeit by a narrow 1.03% margin. Unlike North Carolina, Indiana was not seriously contested again by the Obama campaign in 2012; consequently, Romney was able to carry it by a 10.2% margin and win 6 counties Obama won in 2008.

Obama carried Vigo County, home to Terre Haute, and at the time a noted bellwether; before 2020, it had voted for the winner of every presidential election all but twice since 1892. After 2012, demographic change and the rightward turn of exurban areas accelerated by the Trump era have made Vigo County generally uncompetitive to the present day. As of the 2020 presidential election, this is the last time that Delaware, LaPorte, Perry, Porter, and Vigo counties have voted for a Democratic presidential candidate. Obama won nine counties compared to 83 for Romney, who won most rural areas of the state. Romney also performed well in the Indianapolis suburbs; Allen County, home of Fort Wayne; and Vanderburgh County, home of Evansville. As expected, Obama did better in urban, densely populated areas. Obama trounced Romney in Marion County, home of Indianapolis, as well as Lake County, home of Gary and East Chicago. Obama also for the most part did well in counties that contained major colleges, such as Monroe County, home of Indiana University Bloomington; St. Joseph County, home of the University of Notre Dame in South Bend; and Porter County, home of Valparaiso University.

Incumbent President Barack Obama ran unopposed, securing 221,466 votes.

Republican Nominee Mitt Romney won every pre-election poll conducted in the state by at least 5%, and often by double digits. The average of the final three polls had Romney leading Obama 51% to 43%.

Results
Following Romney's win in Indiana, The Indianapolis Star said that "Voters painted Indiana bright red on Tuesday- with a splash or so of blue" and that "voters also proved that while this state is conservative, it doesn't like to stray too far from the middle".
