Election 2016: The States That Have Changed Political Parties the Most

  • Print

As the 2016 presidential election ramps up, candidates are paying extra attention to the all-important swing states. These states, like Ohio, Florida and Colorado, tend to be the most narrowly divided and can tip the scale of an election.

 

Unsurprisingly, these swing states receive a disproportionate amount of political spending during campaign season.

With that in mind, InsideGov looked back at the states that have historically changed political parties the most. Using presidential election data from 1932 (FDR’s first election) to 2012, InsideGov tracked each state’s voting behavior.

The visualization below shows how each state has voted over time (press play to begin):

Louisiana takes the top spot as the state with the most political flip-flops, having changed parties 11 times since the 1932 election. The next state should come as no surprise: Ohio. Currently one of the most important swing states, Ohio has switched parties 10 times. In the 2012 election, Ohio received the third highest amount of political ad spending in the country.

On the other end of spectrum is Alaska, which has been the most politically consistent state, changing parties only two times. This is partially due to Alaska’s relatively short period as a state.

Behind Alaska are 10 other states that have only switched political parties three times since 1932: Ariz., Idaho, Kan., Maine, Neb., N.D., Okla., S.D., Utah and Vt. Interestingly, most of these states, with the exception of Vermont and Maine, have been consistently Republican over the last three to four decades.
