Big name celebrities have not shied away from expressing who they are supporting various candidates this primary season - from Katy Perry, Beyonce, Neil Young, Rosario Dawson, Spike Lee, and the list goes on.

Sanders spoke Saturday at a rally in Kimball Park.

Sanders discussed his customary topics -- getting big money out of politics, his plan to make public colleges and universities tuition-free, combating climate change and ensuring universal health care, the campaign official said.

An estimated 12,000 people attended a Sanders rally at the San Diego Convention Center in March. Sanders supporters began lining up for the event Saturday morning, just a few miles away from where Bill Clinton appeared.

Sanders was also scheduled to speak in Vista on Sunday at 2 p.m. at Rancho Buena Vista High School.
