Double endorsements: What’s the point?

So, late yesterday Irwindale Councilman Larry Burrola announced that in addition to supporting Sen. Gil Cedillo for Congress, he would also be endorsing Board of Equalization Chairwoman Judy Chu.

Burrola is not the only one endorsing both Congressional candidates; so is Baldwin Park Mayor Manuel Lozano.

It raises the question: What good is it to endorse two candidates? After all, it’s not like we can vote for two people for one seat.
