I took a look at the Republican Presidential election returns for California and found an interesting dynamic at play.
McCain (according to the counting so far) has won 50 out of 53 Congressional Districts in California. But he faces a much-discussed challenge to pull the various factions of the Republican Party together if he does become the Republican nominee.
This challenge is illustrated by a new twist on the Inland / Coastal division in California:
The traditional inland/coastal split in California is between Republican-leaning counties inland and Democratic-leaning counties on the coast. But the two maps below show a similar divide exists among California’s Republican voters.
By combining the votes of McCain and Giuliani and comparing them to the combined votes of Romney, Huckabee, Keyes, Tancredo, Brownback and the other (more traditionally conservative) Republican Presidential candidates I found that (at this time) McCain / Giuliani carry 16 Congressional Districts and Romney/Huckabee/etc. carry 37.
McCain/Guiliani (blue) v. Romney/Huckabee/etc. (green)
The 16 districts won by McCain/Giuliani are surprisingly concentrated, with 13 the San Francisco Bay Area and northern coast, and three heavily Democratic districts in LA and Orange Counties.

Even within the Republican Party, it seems, there is an inland/coastal split. If McCain hopes to make California competitive, he will have to bridge that divide while maintaining his appeal among independent voters.
