>Bluest county: Cherokee County
Cherokee County is the bluest county in Oklahoma. While Romney received the majority of the county’s votes, 43% of the county’s 14,288 votes went to Obama, the highest share of any county in Oklahoma. By contrast, 33% of voters across the state supported Obama. As in Democratic-leaning areas in other states, less than half of Cherokee County identifies as white, far lower than the 62.8% of Americans who identify as white.
>Bluest county: Multnomah County
Multnomah County, which includes the city of Portland, is the bluest county in Oregon. More than three-quarters of the county’s roughly 350,000 votes were cast for Obama in 2012. Additionally, all three of the congressional districts making up parts of the county are represented by Democrats.
>Bluest county: Philadelphia County
Obama won 85.2% of the votes in Philadelphia County, the largest share of any county in Pennsylvania. In addition to voting for a Democrat for president, all three congressional districts located in the county sent a Democrat to the House in each of the last five congressional elections. Like other predominantly Democratic areas, 36.2% of county residents identify as white, and median household income is $37,460. By comparison, the 62.8% of the U.S. population identifies as white and the national median household income is $52,046.
39. Rhode Island
>Bluest county: Providence County
Obama won 66.6% of the votes in Providence County. Every county in the state cast a majority vote for Obama but the share from Providence was the largest. Voters in both districts in Rhode Island, which contain Providence as well as Bristol, Kent, Newport, and Washington counties, have helped send Democrats to the Senate and House in each of the past five election cycles.
40. South Carolina
>Bluest county: Allendale County
Obama won 78.3% of the votes in Allendale County, the highest share of any county in South Carolina. In addition to sending a Democrat to the White House, the county sent a Democrat to the U.S. House of Representatives in each of the last five congressional elections. Democratic politicians are more likely than their Republican rivals to garner support from financially insecure voters, and this could partially explain the Democratic-leanings in Allendale. County residents have a median household income of $25,495, less than half the national median household income of $53,482.
