My colleague Shane Goldmacher
wrote two great dispatches
about Stark's latest outburst against a former California legislative leader who endorsed Swalwell. Even though there's no chance the seat will change partisan hands, it's one of the most interesting races in the country because it's a testing ground for some of the dynamics at play under California's new primary system.
One of the questions we're most interested in answering is what Republicans will do in this and other California districts with two Democrats (or two Republicans) in the general election. They could end up just not voting for a member of Congress; even California's veteran political operatives aren't sure what will happen. Keep an eye out for more coverage from Hotline On Call
-- and the San Francisco Chronicle
, of course.
