Roosevelt ran ahead of his nationwide total in all three Pacific states, getting 66 percent in California and Washington, and even in Oregon, which was regarded as the most Republican of western states, he got 64 percent of the vote.
Roosevelt had ran slightly below his nationwide total in 1932 in all three states, and his 1940 and 1944 levels in all three states were closer (or below, in Oregon's case). And by 1948, only Washington was more Democratic than the nation as a whole (due to the strong union presence in that state).
So why did he do so ridiculously well in the Pacific states in 1936?
On a side note, Roosevelt "only" got 64 percent in Seattle, 68 percent in Portland and 71 percent in San Francisco - three cities where Obama got over 80 percent of the vote!
