WTF happened in Lassen County? Kashkari lived around Lake Tahoe for awhile when he decided to go all mountain man, but that isn't Lassen...
Lassen County is one of a number of traditionally working class counties in the West that ditched the Democratic Party in the 90s due to industrial decline, the death of the Greatest Generation and the Democratic Party's preoccupation with the environment and social issues.
Look at Clearwater County in Idaho or Coos County in Oregon and you'll find the same trend: retired/former loggers hate the Democratic Party.
Lewis County in Washington is another example.
