Like other areas of the sparse Alaskan Bush with large Alaska Native majorities, the Yukon-Koyukuk Census Area often favors the Democratic Party relative to the state as a whole. Though it voted Republican in all presidential elections in the 2000s, it has supported the Democrats more recently by nearly 30-point margins.
