U.S. Representative Summer Lee, a progressive Democrat representing the Pittsburgh area, has secured a strong lead in the mail-in ballot count for her reelection bid. Allegheny County, which makes up 90% of Pennsylvania’s 12th Congressional District, has tabulated the majority of mail-in ballots, showing Lee ahead of her challenger Bhavini Patel by a margin of 55% to 45%. This puts Lee in a favorable position to retain her seat, despite historically performing weaker among mail-in voters.
