Neel Kashkari's victory -- actually, a second-place showing in the top-two primary won't bring California Republicans into the sunshine, but it may keep them from digging deeper into the hole.
California is a blue state, but that doesn't rule out future victories for Republicans not named Schwarzenegger. States that are even bluer than California -- New York, Rhode Island, Massachusetts, Hawaii, and Maryland -- have all elected Republican governors. The challenge is to find a well-qualified candidate who can hold onto the GOP base and appeal to other voters.
Kashkari will have a hard time beating Brown. But if he can hold his own, he can open the door for other Republican candidates in 2018 and beyond.
