Something interesting I stumbled upon last night.

In late 1941, the people of Northern California and Southern Oregon, angered by underrepresentation in their state governments, as well as the tendency of those governments to take the valuable resources, such as copper and timber, found in the area but neglect to invest in the area's infrastructure (it took until 1939 for much of the region to get electricity, and the roads were terrible), rose up in "patriotic revolt". They set up roadblocks and declared the formation of a new U.S. State known as Jefferson, with a temporary capital located in Yreka. Several counties in both California and Oregon signed on to become part of the new state.
The movement was strong for two weeks, even electing a provisonal governor, but the death of one of it's major proponents (Mayor Gilford Gable of Port Orford) followed quickly by the Japanese attack on Pearl Harbor, led to the movement's collapse. Most Jeffersonians shifted their focus from secession to the war effort, and much of their grievances wound up being addressed anyway without need for secession - the U.S. government wound up improving the roads in the area in order to access the copper and chromite necessary for the war effort.
So, had the U.S. entry into WW2 been delayed for a substaintial amount of time (let's say a year or two), is there any chance that the Jeffersonian statehood movement could gain enough momentum to become a serious proposition? Or would it have just resulted in the same thing as OTL, with the government fixing a few roads and everyone going home?
