OAKLAND, Calif. (KTVU) - Voters who waited to the last minute to register for California's June 7th primary had a few options to meet the deadline Monday.
Alameda County's Registrar Tim Dupuis stood with his staff at a pop up a tent outside the Oakland office on Oak Street, accepting voter registration cards until midnight. Voters were also able to register online at the state and county websites through midnight.
"I love the tent. I'm so glad they're out here and visible and everyone can see them," said Florene Wiley of Oakland who recently moved from New York and needed to register, "I am undecided, I'm an undecided Democratic."
With the Democratic Party presidential nomineen still undecided, many elections officials say they've seen a stream of voters changing their party affiliation.
Both the Democratic frontrunner Hillary Clinton and Senator Bernie Sanders are hoping for a big win in California. The state's Democratic primary allows "no party preference" voters to request a Democratic ballot and vote in the primary.
"It feels like for the first time California might have some kind of say instead of it being oh, it's California. It's June, no big deal," said Allison Tom of Oakland.
Both Clinton and Sanders claim they are better able to beat Donald Trump, the presumptive Republican nominee.
"If Democrats want to be certain that Donald Trump never becomes president - our campaign is the strongest campaign," said Sanders on Monday.
Clinton leads Sanders in peldged delegates and plans to attend a Bay Area fundraiser in Atherton Wednesday evening.
"The only thing standing between Donald Trump and the Oval Office is all of us. We are coming to the end of the Democratic primaries," Clinton said Monday at a rally in Detroit.
The Real Clear Politics average of recent national head-to-head polls shows Republican Donald Trump with a razor thin edge over Hillary Clinton. Trump's popularity has received a bump since he became the presumptive nominee three weeks earlier.
Some early voters are already dropping off their ballots.
"We just wanted to make sure the ballots got to where they need to be," said Dylin Redling of Oakland.
Supporters of both Clinton and Sanders are hoping they can win over some Independents and Republicans.
"I want to support Bernie Sanders and so I just made sure that I could switch over to Democrat," said Tyrone Schiescler, of Oakland who showed up to change his registration.
"I talked to a gentleman who had been a Republican for 64 years and he changed his registration to Democrat last week so he could vote for Bernie Sanders," said Carolyn Bowden, a Sanders campaign volunteer.
"We're seeing a lot of activity," said Dupuis, "Certainly with the new preisdent that we're going to be electing, we're seeing more interest, so we are seeing a climb in registration at this point."
Dupuis says Alameda County's Registrar's office has already received 25,000 vote by mail ballots.
"For a no-party preference voter, they have the opportunity to cross over vote into one of the three parties that allows that, the Democratic, the American Independent and the Libertarian. They can request a crossover ballot as late as May 31st if they want to vote by mail, or they can request at the polls," Dupuis said.
Some say it could be record turnout this year, and elections officials say they still need volunteers to work at the polls.
"To run an election for Alameda County, we recruit 6,000 pollworkers for the election and of those, 2,000 of them have to be bilingual pollworkers," Dupuis said.
Dupuis says his office will be open Saturday and Sunday for the next two weeks with a drive-by drop off from 9 a.m. until 3 p.m. on Fallon Street.
