The big news out of Indiana was six-term United States Senator Richard Lugar's loss to state Treasurer Richard Mourdock in the Republican primary. The hard-fought battle was the first time Lugar had faced a primary challenge since 1976. Tea Party and national conservative groups poured millions of dollars into the campaign against Lugar, a moderate Republican who sometimes compromised with Democrats.

- All Senate and House incumbents who ran for re-election survived the primary and will go on to the general election. Five other states have held state legislative primaries this year - Indiana is the first where no incumbents were defeated.
- Open seats in District 24, District 34, and District 47 of the Indiana House were decided last night. All three districts held a single partisan primary, in essence virtually assuring the primary winner of gaining a seat in the legislature in November.
- Numerous incumbents in the Indiana State Senate ran unopposed last night in their respective primaries. However, due to a lack of challengers filing to run opposite them in the general election, they will also run unopposed in the general election.
- District 7 incumbent Brandt Hershman (R), District 9 incumbent Ryan Mishler (R), District 33 incumbent Greg Taylor (D), District 34 incumbent Jean Breaux (R), District 42 incumbent Jean Leising (R), and District 44 incumbent Brent Steele (R) will all run unopposed for re-election in the general election in November.
- District 13 incumbent Susan Glick defeated challenger David Yarde in the Republican primary, advancing her to the general election where she will run unopposed for re-election.
- Incumbent Connie Lawson was appointed as the Indiana Secretary of State on March 16, 2012. It was too late for her to withdraw from the primary. Now that the primary has passed, Lawson will withdraw from the Senate race and a replacement candidate will be named via a caucus.
