The swing map of Cali is particularly interesting....
Looking at the Bay Area, you see some of the largest swings towards the Democrats in relatively wealthy areas in the East Bay, like Walnut Creek/Concord rolling all the way down to parts of South Bay especially the NW parts of Santa Clara County, and then all the way up the Peninsula.
Meanwhile you have a trend towards the Republicans in some of the most working-class parts of the region, including some heavier African-American communities in places like East Oakland and Hunters Point are of SF....
Even looking at LA County, there is that major light blue gap in the Middle running through historic Watts/ "South Central" all the way into Northern Long Beach that jumps out as well.
Shift over to the wealthy Coastal communities all the way from halfway through Orange County to Malibu, there are huge swings towards Clinton, not even going into some of the wealthier communities in the Canyons of OC and LA counties....
What is going on with that sea of dark blue in the Middle of Orange County???
Hurts my eyes just looking at it, and don't quite understand the context in that part of the County...
The swing in the african american areas is mostly because of the dropoff in turnout compared to when Obama was on the ballot.
