California’s top two primary could be a disaster for Democrats. It could be for Republicans as well.

You’re going to hear a lot about something called the “top-two” primary in the lead up to California primary. Tuesday’s contest in the Golden State has been described as a potential “disaster” for Democrats in their march to pick up a net gain of 23 House seats and the majority in November.

And while that could eventually be the case, the truth is we have so little data as to be almost totally in the dark when looking at these races, and a look at the little data that is available suggests that such fears are probably overblown. CONT.
