You may be correct about Californicate bring totally D country. But I’m not sure. The R party (Reagan as the clear exception) tends to nominate either totally dull drab boring country club empty suits. Or else known or suspected corruptoids. None can articulate a clear reason why anybody should bother voting for them.
The trend there is really ugly.
Candidates like DiFi and Boxer who won 20 yrs ago by a couple points win by 20+ now.
Here’s the D percentage in POTUS elections:
92 46%
96 51%
00 53%
04 54%
08 61%
12 60%
