Indiana Political History & Voting Patterns
Competitive through 2008; consistently R since. A complete guide to how Indiana has voted in presidential elections, which coalitions have driven results, and how the state has shifted over time.
Historical Overview
Indiana shocked the political world in 2008 when Barack Obama carried it by 1 point — the first Democrat to win Indiana since Lyndon Johnson’s 1964 landslide. That result reflected Obama’s massive turnout operation, his personal appeal, and anti-Bush exhaustion. The state immediately reverted in 2010. Indiana is now one of the more Republican large states, anchored by suburban Indianapolis (Marion County) voting Democratic while the surrounding ring counties and rural areas are deeply Republican. Mike Pence’s term as governor (2013-2017) and VP (2017-2021) gave Indiana unusual national prominence.
