A busload of volunteers left the state Capitol this morning bound for Nevada, where they will work tomorrow and Saturday trying to get Democrats to turn out for Hillary Clinton in Saturday's Nevada caucus. Assembly Speaker Fabian Nuñez, a national co-chair of the Clinton campaign, was on hand to send off the volunteers.

It has become a familiar scene in recent years, as Californians have flocked en masse to battleground states and early primary states to pitch in. And when prominent Californians do that, it can sometimes lead to awkward moments.

On the Sunday before the Iowa caucus, the Clinton campaign held a national conference call to brief prominent national supporters on the situation in Iowa.

According to a Californian who listened in, former Iowa Gov. Tom Vilsack got on the line to say the ground operations were going very well. He noted that a number of members of Congress were in the state to help campaign, and said that just that morning he had been impressed with the work of a Hispanic volunteer he encountered at the grocery store.

"I went over to introduce myself," Vilsack reportedly said. "I told him, 'You probably don't recognize me, but I'm the former governor of Iowa.' And he said, 'You probably don't recognize me, but I'm the mayor of Los Angeles.'"

Never let it be said that Antonio Villaraigosa isn't doing his part.
