The Superregion of the West Coast the most populous in the nation, due mainly to the fact that it includes the state of California. Six of the 30 most populous urban centers in the nation lie entirely within the West Coast; by far, the most of any superregion. (Los Angeles, San Francisco, Seattle, Sacramento, San Diego, and Portland). Despite this high level of urbanization, however, the West Coast is also a major rural powerhouse, representing a significant fraction of America's agricultural output.

The West Coast is named in a purely geographic sense; of the five states which border on the Pacific Ocean, four of them make up this superregion. The fifth, Alaska, is located in Big Sky Country instead.


Adjacent Superregions


The West Coast is a Democratic Stronghold, with Democrats holding an overall 54-46 registration advantage. The advantage is about equal in both regions of the West Coast, but the Pacific Coast region has greater variance, with Hawaii giving Democrats a nearly 2-1 advantage (63-37), Washington a more modest 54-46 advantage, and Oregon actually leaning slightly Republican with the GOP holding a slim 52-48 advantage.

Because of the blue tilt of the superregion and its constituent regions, it is relatively rare for Republicans to enjoy success here. However, both California and the Pacific Coast do contain enough independents to swing red, given the right candidate and right conditions.
