SACRAMENTO, Calif. – “We are coming to California,” U.S. Sen. Bernie Sanders told a rally on Monday as he kicked off a home-stretch campaign push to win the state’s treasure trove of delegates and help “take the political revolution” all the way to this summer’s Democratic National Convention.

“The political establishment is getting nervous,” Sanders told more than 16,000 people at a soccer stadium in California’s capital city. “They should be getting very nervous because real change is coming.”

Sanders already has won 18 primaries and caucuses and amassed more than 45 percent of all pledged delegates going into this summer’s convention to Philadelphia. California will elect 475 pledged delegates on June 7. By then, Sanders could be coming off more wins in the final laps of the presidential primaries and caucuses.
