On the eve of the California primary volunteers working to get people out to vote

FRESNO, Calif. (KFSN) -- We are less than 12 hours away from polls opening on a primary day in California. With several political battles expected to come down to the wire, every minute counts for candidates campaigning across the Valley.

Inside Fresno's Republican Headquarters the phone calls kept going.

While outside volunteers with the Democratic party kept walking.

"Their vote is really going to matter, everything is close in California, especially in this section," said Doug Kessler, Regional Director, Democratic party.

Both parties are working to the very last minute before Tuesday's primary. Printing off names of registered voters and calling, or calling on, each one.

The Fresno County Republican Party left messages for more than 5,500 people the past few weeks. With Democrats coming out in numbers to vote for Hillary Clinton or Bernie Sanders, GOP voters said it's crucial to bump up their numbers.

"A lot of people haven't voted, or they forgot, and this last push is very important," said Fred Vanderhoof, Fresno County Republican Party.

So far, voters have mailed in 63,000 ballots, about 15-percent of the Fresno County electorate.

Democratic volunteers said they hope canvassing the neighborhood in triple digit heat will help them pull off a win.

"It's like oh my gosh thank you. If it was an absentee ballot person, particularly oh I left it on a table, I completely forgot about it. We think we get really good results from this," said Kessler.

It wasn't just the two parties trying to attract voters. Local activists met with those living in low-income areas hoping people will pick a mayor who will fix substandard housing.

"A lot of people aren't aware that the mayoral election is also going to be happening. So we provided information on the mayoral forum that we held and highlighted the significance of them coming out," said Sukaina Hussian, faith leader.

The preparations don't stop here, callers will be on the phones cutting it close Tuesday night.

"Literally 10 minutes before the polls close, we can still get people out there," said Vanderhoof.

Volunteers for both parties are also offering rides to the polls. If you need one, you can contact the party of your choice.
