An egregious error saw nearly 120,000 registered voters bumped from the Los Angeles County voter rolls during Tuesday's jungle primary in California.

County Clerk Dean Logan apologized for the mistake, impacting more than one-third of all precincts in L.A. County, in a Tuesday evening statement.

"We apologize for the inconvenience and concern this has caused," Logan said. "Voters should be assured their vote will be counted.

According to the L.A. County registrar, the 2.3 percent of the electorate — roughly 118,522 voters — left off the rolls may still cast "provisional ballots," yet counting and verifying their authenticity will likely extend the time it takes before the races are called.

In California's nonpartisan "jungle primary," the top two vote-getters in each race — regardless of party affiliation — advance to the general election.

Democrats have targeted the 39th District, part of which falls within L.A. County, as a flippable seat, yet their chances of doing so fell dramatically after Rep. Ed Royce, R-Calif., announced his retirement at the end of his term and multiple, conservative possible replacements announced their candidacies.

Polls in California are scheduled to close at 11:00 p.m. EST/8:00 p.m. PST.
