Election officials in the Democratic-leaning part of New Jersey's too-close-to-call 3rd Congressional District say they're counting vote-by-mail ballots.
Burlington County Board of Election Chairman Joe Dugan says there were about 26,000 mailed-in ballots.
Republican Rep. Tom MacArthur is seeking his third term against Democratic newcomer Andy Kim.
The district includes Philadelphia suburbs in the west and sits in the New York media market in the east.
Dugan says about 20,000 have been counted so far with about 6,000 left to be tallied Wednesday. Those ballots have not been included in results that so far show MacArthur has a roughly 2,000-vote lead.
In the GOP-leaning part of the district, Ocean County Board of Election official Jason Varano says roughly 31,000 mail-in ballots are already reflected in results posted online.
Officials say provisional ballots also remain to be counted.
