Did Carter perform so poorly in the west?
The 3 western coast states were very close, the national result was very close.
Comparing to the national vote, California was R+3,8, Oregon was R+2,2 and Washington was R+5,9.
Eugene McCarthy had some progressive votes.
He did, he lost the entirety in the '76 primaries, he lost the NV/CA/OR/WA by at least R+2 or more (average being R+6).
Then he lost CA/AZ to Ted Kennedy in 1980.
Also Dukakis/Humphrey got the same vote...the former lost overall by 8, and the later was just behind Nixon...while Carter was ahead by 2.
Mondale literally did better in '84 too.
