BAKERSFIELD, Calif. (KGET) -- The tight races in Congressional District 22 and Supervisorial District 5 remain close as ballots are still being counted. Tuesday was the final day the Elections office was receiving ballots to process, unless they need to be cured -- meaning there was an issue with a voter's first ballot and a new ballot must be filed out and sent in to the Elections office to be counted. Less than 50K ballots still left to process from Nov. 5 election: Kern County Elections Office Rudy Salas' campaign was out knocking on doors Tuesday encouraging voters who've had their ballots returned, to correct mistakes and send them back in. "There was approximately 5,600 cure letters sent out and we've received back about, approximately 3,700," said Aimee Espinoza, Kern County's Registrar of Voters. Cured ballots have until Dec. 1 to be returned to the elections office to be counted as a vote. Aside from those, there are still thousands of ballots to process, "We have about 50,000 and that is in different places in processing," said Espinoza. "Definitely by Friday we'll have poll place, anything received before the election, and any ballots received through E+7." "E+7" are the mail-in ballots that were postmarked by Election Day, received by the elections division. These votes are crucial in the tight races remaining in the county. The Supervisor District 5 race between Leticia Perez and Kimberly Salas is the closest with Perez leading by only four votes. The highly competitive Congressional District 22 race between David Valadao and Rudy Salas remained close, with Valadao leading with just over 1,200 votes from Kern County. But districtwide, Valadao is leading by an even larger margin, approximately 9,500 votes over Salas, according to the California Secretary of State's Office. California's 22nd Congressional District is described as a purple district, meaning it could swing either way. And late Tuesday evening, the Associated Press called the race for Valadao. 17 News reached out to all of the candidates in these two races but have not heard back from them. Leticia Perez, declined to give comment. Late Tuesday afternoon, elections officials said approximately 33,395 ballots still need to be processed.
