The 2012 United States House of Representatives elections in Indiana were held on Tuesday, November 6, 2012, to elect the nine U.S. representatives from the state, one from each of the state's nine congressional districts. The elections coincided with the elections of other federal and state offices, including a quadrennial presidential election, an election to the U.S. Senate, and a gubernatorial election.
A redistricting bill was passed by both houses of the Indiana General Assembly in April 2011 and signed into law by Governor Mitch Daniels on May 10, 2011.
The newly drawn map was designed to produce seven districts which are favorable to the Republican Party and two which favor the Democratic Party. Republicans described the districts as being more compact and more in keeping with existing county boundaries than the previous map, while Democrats argued that the map was intended to protect Republican incumbents and help the Republican Party win the 2nd district.
The district, based in the suburbs and exurbs of Chicago, acquired parts of LaPorte County, including Michigan City, in redistricting.
In redistricting, parts of the state which typically favor Republicans, including Elkhart County, Miami County, Wabash County and much of Kosciusko County, were moved into the 2nd district, while Democratic-leaning areas such as Kokomo and part of LaPorte County were removed from the district.
Prior to announcing his Senate campaign, Donnelly commented that he was confident that a Democrat would be able to win the district, noting that then-Senator Barack Obama would have received 49% of the vote in the district in the 2008 presidential election had it been held under the newly drawn boundaries.
Andrew Straw, an attorney, switched from the Democratic Party to Green Party and ran for this seat. Straw was an Indiana Supreme Court analyst and an assistant dean at the Indiana University Maurer School of Law in charge of the International Program. He was, however, disqualified from the ballot in July.
The 3rd district was expected to remain favorable to Republicans. Among the changes made in redistricting were the removal of Elkhart County from the 4th district to the 2nd, and the addition of areas south of Fort Wayne, which might have made Stutzman vulnerable to a primary challenge.
Republican incumbent Todd Rokita ran for re-election in 2012. Rokita's home lies "about 500 yards" outside the boundaries of the newly drawn 4th district, a phenomenon he attributed in May 2011 to "a kind of comeuppance thing" on the part of members of the Indiana General Assembly in return for his having supported a nonpartisan redistricting process during his tenure as Secretary of State of Indiana. Sue Landske, a Republican member of the Indiana Senate, denied that this was the case. The 4th district was expected to remain favorable to Republicans.
The 5th district continues to include Hamilton County and the north side of Indianapolis, but received Democratic-leaning areas in northern Marion and Madison, and lost rural areas near Fort Wayne. The district was expected to continue to favor Republicans.
Republican incumbent Dan Burton, who had represented the 5th district since 2003 and previously represented the 6th district from 1983, retired rather than seeking re-election in 2012.
The 6th district was made more favorable to Republicans in redistricting, and now stretches from Muncie to the Ohio River.
Republican incumbent Mike Pence announced in May 2011 that he would run for Governor of Indiana rather than for re-election to the House of Representatives.
The 7th district lost Democratic-leaning areas in northern Marion County in redistricting, while acquiring more Republican areas in the south of the county. Nonetheless, the district was expected to remain favorable to Democrats.
The 8th district was made slightly more favorable to Democrats in redistricting, as a result of the removal of Fountain County, Putnam County and Warren County, all of which favor Republicans, and the addition of Dubois County, Perry County, Spencer County and part of Crawford County, all of which strongly favor neither party. Republican incumbent Larry Bucshon ran for re-election.
The 8th district's Democratic candidates agreed to participate in a caucus in which the chairs and vice chairs of 38 counties would vote to decide the party's nominee; after which the candidates not selected would support the winner. Former state representative Dave Crooks was endorsed as the Democratic nominee by party leaders on December 10, 2011.
The 9th district previously consisted mostly of rural areas in southeastern Indiana but was made more favorable to Republicans when the legislature extended it northwards to include Johnson County and Morgan County while also incorporating suburbs of Louisville, Kentucky. Republican incumbent Todd Young ran for re-election.
Jason Sharp was nominated by the Libertarian Party but later dropped out.
