Judge rejects GOP bid to restrict overseas ballots in Pennsylvania

Voters can "receive a ballot by email and then vote a ballot without providing identification at any step in the process," the Republican plaintiffs alleged.

He also cited procedural issues with the case, noting they failed to produce evidence or articulate a "viable course of action."

"An injunction at this late hour would upend the Commonwealth's carefully laid election administration procedures to the detriment of untold thousands of voters, to say nothing of the state and county administrators who would be expected to implement these new procedures on top of their current duties," Conner said.

The push comes as Republicans in at least three swing states have sought to crack down on overseas voting in the final sprint to Election Day. The RNC and state-level groups in Michigan and North Carolina have also filed lawsuits in recent weeks seeking additional restrictions on a vetting and verification process they argue is devoid of proper safeguards.

Pennsylvania has 19 on its own, giving it outsize importance in the election.

Earlier this month, a lawyer testified to the court that over 26,000 overseas ballots had already been cast in Pennsylvania. It's unclear how many of those would be impacted by a court decision.
