Clinton has 46 percent support to Sanders's 44 percent, according to The Public Policy Institute of California survey released Wednesday.


When the poll results are filtered down to just registered Democrats, Clinton leads Sanders, 49 percent to 41 percent.

California's June 7 contest is an open primary, meaning voters who are not registered Democrats may participate. The state offers 475 pledged delegates — the largest total of any state.

There is little gender gap in the poll totals. Sanders had 46 percent of men, with Clinton garnering 42 percent. Among women, Clinton led with 49 percent support to Sanders's 42 percent.

Clinton’s campaign has declined Sanders's call to face off in another debate before the California primary.

Sanders called the move “a little bit insulting” to California voters, adding he was “not surprised” by Clinton’s reluctance.

Clinton has a significant edge in both pledged delegates and superdelegates, but Sanders has vowed to keep fighting up until the Democratic National Convention this summer.

The poll of 552 Democratic-leaning voters in California was conducted from May 13-22 via cell and landline telephone interviews. It has a 5.7 percent margin of error.
