Vermont Sen. Bernie Sanders held a rally in Mission Valley Sunday afternoon, two days before the California primary brings his last chance to prevent rival Hillary Clinton from clinching the Democratic nomination.
A number of bands performed and political activist Cornel West spoke at the event at the parking lot of Qualcomm Stadium before Sanders addressed about 4,000 of his supporters.
The Vermont senator said he can solve the country's problems by leveling the economic playing field.
“We are tired of perhaps being the first generation in modern American history to have a lower standard of living than our parents,” Sanders said.
He also recounted a number of the social changes that have taken place over the last century.
“Real change never takes place unless millions of people are prepared to make that change," Sander said.
Sanders previously spoke to an estimated 12,000 people in March at the San Diego Convention Center and made appearances last month in National City and Vista.
