California’s elections are never quite over on Election Day, and this year is no different. The state’s big population and its universal vote-by-mail system add to the time it takes to count the large volume of ballots counties will receive.

California primary results may take weeks due to mail voting laws, sparking criticism from analysts like Nate Silver who call it embarrassing.

The Republicans are currently in position to advance in California’s key races but thousands of late ballots still remain.

Southern California voters awaiting final returns from Tuesday’s primary election should expect vote totals to continue changing for several weeks as counties count outstanding ballots, California Secretary of State Shirley Weber said Thursday amid allegations by President Donald Trump of election cheating.

Election veterans say its a "demanding" and "exhausting" process.
