Congressman Tim Bishop is headed back to Washington for a sixth term.

Two years after it took 36 days for the Southampton Democrat to claim victory over opponent Randy Altschuler, it took him less than three hours to deliver an acceptance speech Tuesday.

“My opponent may have had the guys with the big checks,” Mr. Bishop told supporters at the Islanda Marriott. “I had the guys with the big hearts.”

Mr. Bishop secured 132,525 votes to 121,478 for Mr. Altschuler, a Republican businessman from St. James.

The Congressman, who garnered 52 percent of the vote Tuesday, had defeated Mr. Altschuler by just 593 votes in 2010.

Mr. Bishop, who was also celebrating President Barack Obama’s reelection Tuesday night, will still be in the minority next year as Republicans kept control of the U.S. House of Representatives.

“We’ve got serious problems to solve in this country and I very much hope now that a very, very brutal election season is behind us, we’ll set partisan differences aside and try to resolve issues for the American people,” Mr. Bishop said. “The dysfunction over the last two years certainly demonstrates that hyper-partisanship doesn’t work. We’ve tried that, we’ve now had an election, the president was reelected, so now let’s go to work to support the American people and businesses.”

Mr. Altschuler said thanked his supporters and credited his opponent in a concession speech delivered at Emporium in Patchogue shortly after midnight.

“I’m going to go home and spend time with my family and help the community,” said Mr. Altschuler, 41. “Congressman Bishop ran a good campaign.”

Mr. Bishop was one of several area incumbents to claim a win Tuesday, with Senator Ken LaValle (R-Port Jefferson) and Assemblyman Fred Thiele (I-Sag Harbor) winning reelection with landslide victories.

Mr. LaValle, 73, is now, along with Schenectady Republican Hugh Farley, the longest tenured New York State Senator. Both men were first elected in 1976. Senator Owen Johnson, also from Suffolk, did not seek reelection this year after serving since 1972.

Mr. LaValle secured 60 percent of the vote Tuesday over Southampton Councilwoman Bridget Fleming, a Democrat from Sag Harbor.

Mr. Thiele, 59, ran unopposed. He has held a seat in the Assembly since 1995 and will represent Shelter Island beginning next year.
