After a blue wave swept across the country late Tuesday and seemed to lift several Democrats in Utah, too, based on early returns, some voters are wondering how many ballots have yet to be counted in the state.

In Utah, though, that number isn’t so easy to pin down the morning after Election Day. There doesn’t appear to be one statewide, real-time tally of outstanding ballots, and county clerks are still compiling their numbers.

A spokesperson for Lt. Gov. Deidre Henderson’s office, which oversees elections in Utah, said Wednesday that counties are required to post election statistics by the end of the day, including how many ballots remain uncounted.

Those reports will be available on the state’s election reporting website once counties submit them.

In the meantime, county clerks are working to tally their own numbers throughout the day, and some have begun sharing estimates online.

In Davis County, for example, the clerk’s office said Wednesday morning that about 30,000 ballots still need be counted. The county’s election website reported 86,932 ballots had been cast, with voter turnout at 43.4%.

Farther north early Wednesday, the Weber County clerk’s office estimated that about 17,000 ballots still needed to be counted.

Salt Lake County is working on a much larger backlog: As of Wednesday afternoon, more than 100,000 ballots remained uncounted, Deputy Clerk Nikila Venugopal said.

She added that the county didn’t expect to release any additional election results Wednesday night, though the county would still submit its required voter statistics.

The tallies are smaller in less-populated counties. For example, the Box Elder County clerk’s office reported approximately 3,000 ballots were still uncounted Wednesday morning, while Rich County had just 38 left to count.

Some races span multiple counties, based on a seat’s district boundaries. Until counties are able to understand how many ballots still need to be counted, it’s not possible to know the exact number of votes that still need to tallied for individual races.

The Associated Press is another source for tracking results.

It gathers vote totals from county election offices and other official sources, then estimates how much of a race’s vote remains outstanding.

To make that estimate, the AP looks at expected voter turnout based on recent elections, information about early voting and, as results come in, actual vote totals. The estimate is not an exact count of outstanding ballots and can change as election officials report more results.

Counties in Utah can continue counting eligible ballots — including provisional ballots that require additional checks — up until they review and certify their own results, known as a canvass.

County canvasses happen between Nov. 10 and Nov. 17. A statewide canvass will then be done on Nov. 23.
