California election officials continue their efforts to review and count as many as 4 million ballots from the Nov. 8 election, a daunting process that has kept a few closely watched races in limbo for almost a week. A report from the secretary of state’s office on Tuesday put the total number of unprocessed ballots at 4.1 million, down from the previous high of more than 4.5 million reported on Monday. But a closer look at the report reveals that it’s not entirely clear how to estimate the total number of uncounted ballots. Most notably, several counties have not updated their official count since the middle of last week. That could mean hundreds of thousands of ballots have, in fact, been counted — but just not reported to state officials.
