Hawaii is rated as the most Democrat-leaning state in the nation.
According to World Population Review, Hawaiians vote for Democrat candidates 18 percent more than the average American voter does. Second place is Vermont, Socialist Sen. Bernie Sanders’ country; and third place is New York, where Democrat lawyer Andrew Mark Cuomo is governor.
Ohio, North Carolina, Iowa and Florida are the states closest to the average, in other words, they are the most swing states of all, but slightly to the Republican side.
Wyoming is the most Republican-leaning state, with a 25 percent Republican swing off the U.S. average, followed by Oklahoma and Utah, then Idaho and West Virginia.
The calculation is called the Cook Partisan Voting Index, also known as the CPVI. It measures how strongly a state leans Republican or Democratic compared to the entire nation. The index is updated after each presidential election, looking at the average Democratic or Republican share of the last two presidential elections compared to the national average.
Alaska is nine points off of the average, toward the Republican side of the scale.
