And then there were 3. Democrat Seamus Bonner conceded his challenge to Rep. Nick Micozzie, the Delaware County Republican said Thursday.

“I recognize that I was re-elected due to the bipartisan support I received from Democrats, Republicans and Independents,” said Micozzie. “Thank you to the voters for their continued faith, trust, and support.”

His campaign said Bonner, a U.S. Army veteran, threw in the towel after preliminary results showed him too far down.

“Although the votes from those provisional ballots will not be counted until tomorrow, the number would make it impossible for Micozzie’s opponent to overcome the existing 354 vote deficit from the machine vote totals and the more than 100 vote advantage Micozzie earned from absentee ballots, as reported by official poll watchers who observed the precinct counts on election night,” his campaign wrote.

The Obama surge along with a vigorous field effort boosted Bonner.

Micozzie, 82, has been representing his Delaware County district since he won election in 1978. It includes parts of Darby, Upper Darby Township and Lansdowne.

Just 3 races have yet to be called. Rep. Rick Saccone (R-Allegheny) narrowly leads David Levdansky the 39th district (by 30-50 votes or so), with provisional ballots still outstanding. Rep. Justin Simmons (R-Lehigh) is ahead in his re-election battle with Dem Kevin Deely. And Rep. Tom Quigley (R-Montgomery) is awaiting final confirmation of the numbers but is apparently headed for a loss to Dem challenger Mark Painter.

Republicans picked up the seat of retiring Rep. Bud George (D-Clearfield).
