Why did Johnson do so well in Colorado, AK, and the PCNW in 1964?

[Sir Mohamed]

Here’s the PVI map from 1964

Pretty surprised CO was more dem than DE and IL

And CA as well. Johnson only got 59% in CA since wealthy businessmen in Orange County largely supported Goldwater, just keeping Johnson under 60% statewide.

My theory is that the Johnson/Humphrey ticket heavily appealed to farmers while Goldwater's extreme libertarian views on economic/agriculture policy were supposed to hurt farmers.
