US Democratic presidential candidate Bernie Sanders is predicted to beat Hillary Clinton in California in the state’s primary election on June 7.

An analysis of California polls from Political Analyzer found that Sanders, a US Senator from Vermont, is on pace to win 61 percent of the votes in America’s most populous state.

“The current situation in California tells us that the strength of the Vermont Senator is still great and he’s by far the most popular politician,” the analysis found.

The Sanders campaign has been undaunted at the challenge of catching up to Clinton, even though it would require taking more than 60 percent of delegates in the remaining states.

Sanders has said repeatedly that he plans to stay in the race until all states have voted.

“You remember in mid-March after a string of losses, the media wrote his political obituary and we came back to win eight in a row,” Bernie’s wife, Jane Sanders, said according to Politico. “So we’re expecting to do the same here.”

The campaign is also hopeful that they will perform better in the states to come, which have open primaries. They are mostly finished with the closed primaries, which Sanders said takes away his advantage of appeal among independent voters.

“Four out of the five contests that were just done last Tuesday were closed primaries again,” Jane said. “The open primary, Rhode Island, we won. Connecticut, we came very, very close, and if it had been an open primary, we have no doubt we would have won. Pennsylvania, we would have come close or won.”

But many pundits have noted that Sanders can still win even without securing the Democratic Party’s presidential nomination.

By winning as many delegates as possible, he would have more sway at the Democratic National Convention in June and could have more part in shaping the party's agenda.
