Brewster defeated Republican challenger Nicole Ziccarelli by 69 votes.

Ziccarelli has asked a federal judge to throw out 311 mail-in ballots because voters forgot to date the outer envelope when they mailed the ballot back in. Since the ballots were received on time, the state Supreme Court ruled they could be counted even though state law says ballots must be dated by the voters.

If they’re not counted, Ziccarelli wins by 24 votes.

In the meantime, Senator Jake Corman, who is the top Republican in the state Senate, says Republicans would not necessarily abide by the judge’s decision, especially if it was made on procedural grounds.
