When it comes to elections, Washington state as a whole is considered a blue state. It hasn't voted a Republican into The White House since Ronald Reagan in 1984. That's due, in part, to a larger concentration of left-leaning voters in the state's higher population centers. The farther out you get from the Puget Sound area, the more red you're likely to see on an election map.
24/7 Wall Street analyzed voting patterns for both the U.S. House and U.S. Senate over the past five congressional cycles, and from the 2012 presidential election, to come up with the most Democratic and most Republican county in each state. Read the methodology here
One might think the bluest county in Washington is King, Snohomish, or Pierce County. But the analysis shows it's San Juan County – the group of islands located between the mainland and Vancouver Island.
"In San Juan County, Obama won 67.1% of the votes, the second highest share of any county in Washington. In addition, the county voted to send a Democrat to the U.S. House of Representatives in each of the last five congressional elections," writes 24/7 Wall Street
The reddest county is Garfield in southeast Washington.
"Of the 1,275 votes cast in Garfield County in 2012, 912, or 71.5%, went to Romney. Though the number of votes was relatively small, the share of votes cast for Romney was larger share than in any other county in the state. In addition, in each of the last five congressional elections, the county sent a Republican to the U.S. House of Representatives," writes 24/7 Wall Street.
