TOMS RIVER — One of the closest Congressional races in the country remained a toss-up, as just over 2,000 votes separated incumbent Republican Tom MacArthur and Democrat challenger Andy Kim.

MacArthur did not address his supporters in the 3rd Congressional District on Tuesday night and was expected to issue a statement on Wednesday, Ocean County GOP chairman George Gilmore told CBS Philly. Mail-in ballots still need to be counted, according to Gilmore.

No mail-in, provisional, or overseas ballots had yet been counted in Burlington County, according to the county website.

Gilmore did not yet return a message on Wednesday morning.

Democrats saw important victories throughout New Jersey Tuesday night as unofficial election results came in from critical races. New Jersey Democrats flipped at least three House seats, taking at least 10 in all. Republican Chris Smith won re-election in the 4th Congressional District.

With 99 percent of the votes counted from 565 of 571 precincts, MacArthur had a 2,300-vote lead, according to the Associated Press' count.

  • Tom MacArthur, GOP (i) 136,408 — 50 percent
  • Andy Kim, Dem 134,093 — 49 percent
  • Lawrence Berlinski, Ind 3,632 — 1 percent

Kim tried to keep his supporters positive when he addressed them on election night.

"We've got a little bit longer to go. And I want you to believe in this," he said to cheers.

A Monmouth University poll released last Thursday showed the district, which goes across the state from the Philadelphia suburbs to Ocean County, was strongly divided geographically. Kim had a 59-36 percent lead in the western areas of the district but MacArthur led along the shore, 60-34 percent.
