When will we know? · Pennsylvania

When will we know Pennsylvania’s 2026 election results?

In 2024, about 15% of Pennsylvania’s vote was counted by 9 PM ET, 67% by 11 PM and 91% by 1 AM.

It had not passed 95% by 2:37 AM ET, the last overnight copy in the archive (94%); the archive has no later copy for Pennsylvania.

Bucks and Chester were still under 90% at 2:37 AM ET and came in last. Allegheny and Lancaster came in first.

Polls in Pennsylvania close at 8 PM ET.

Each percentage is of that county’s own final count, not of the state’s. “none” means the feed showed no votes yet; “not measured” means the feed did not carry the county’s count at that time, which is not the same as zero. A time after 2:37 AM is the first archived copy at that level; the archive has no copy between 2:37 AM and 2:37 PM on Nov. 6, so the count may have passed it earlier.

What comes late, and why

Medium pace. Mail ballots cannot be processed until 7 a.m. on Election Day; the first results are mostly mail, then a mix, and votes counted after Election Day are mostly mail. In 2020 Trump led until about 61 hours after polls closed; in 2022 large late batches came from Philadelphia and Delaware, Bucks and Montgomery counties. MIT: 95% of the 2024 vote in 8 hours (49 in 2020).

Sources and method

Counts
The New York Times presidential county results feed (Associated Press data), President only, as the Internet Archive’s Wayback Machine kept it. Copies used: 7:59 PM ET Nov. 5 to 2:37 AM ET Nov. 6. The archive has no capture of this feed between 2:37 AM and 2:37 PM ET on Nov 6 2024; a state still counting at 2:37 AM is not measured again until the afternoon (and only the 16 states with an 'after' point carry later captures).
Final count
NYT total_expected_vote per unit in the last archived capture of Nov 8 2024 (statewide 7,048,450), or the largest count seen where that was lower. It is the feed’s last archived value, not a certified canvass.
