Poll workers in Philadelphia are still slogging through mail-in ballots, counting roughly 40 percent of more than 350,000 sent in, city officials said Wednesday morning.

Ballot-counting in the City of Brotherly Love was ceased Tuesday night after workers got through about 76,000 of the 351,069 total that were sent in.

Lisa Deeley, one of three city commissioners in Philly, said about 141,000 mail-in ballots have been counted so far, representing about 40 percent.

The city’s election results website shows exactly 141,523 had been counted as of 4:45 a.m.

On CNN Wednesday morning, City Commissioner Al Schmidt said workers are bracing for between 350,000 and 400,000 mail-in ballots to come in.

“As you can see behind me, we have a team working just day and night until every vote is counted in Philadelphia,” he said.

Asked how long the count would take, Schmidt urged patience.

“With 350,000 or more to count right out to the gate, it will take some time,” he said. “If everything keeps up, we’ll have the total results in the next couple of days.”

He also noted that Pennsylvania allows votes to be received and counted up until Friday.

“We can’t count what we don’t yet have,” he said.

As of 10 a.m. Wednesday, Joe Biden had 77.5 percent of the vote in Philadelphia, while President Trump garnered 21 percent.

Pennsylvania is one of the handful of swing states that have yet to deliver election results in one of the most contentious presidential elections in history.
