California: How Demographic Changes Impacted Partisan Changes (Part 4)

For the final leg of our journey, we are going to the Southland, which includes the 3 biggest counties in the state. Back in 1910, these counties held just about 30% of the state’s population, while the Bay Area held 40%. Now, the Southland’s slice of the pie has been pumped up to 55%, while the Bay Area holds barely 20%. Looking at the PVI results from 1992, it made perfect sense for Clinton to focus his California efforts more on SoCal, because it was making up a greater share of the state. His efforts plus the demographic changes already underway played a big part in pulling this very populous region, and the state, leftward.
