As election season comes into its final weeks, the battle for the 1st Congressional District has taken a bitter turn.

Incumbent Democrat Rep. Tim Bishop is once again facing off against Republican Lee Zeldin. The district they're vying for stretches from the Town of Smithtown all the way to Orient and Montauk Point, and its voters have elected both Democrats and Republicans throughout the years.

In recent campaign ads, both sides have been slinging heavy criticism. The latest Zeldin commercial accuses Bishop of dishonesty, while Bishop's camp claims Zeldin's extreme politics hurt women.

Bishop believes the race comes down to experience: he's held the office since 2002. "I know the needs of the district and I've delivered for them," he says, noting that his proudest accomplishment is that his office has resolved more than 17,000 constituent service cases.

Zeldin argues that Washington needs fresh faces. "We can't change Washington unless we change who we send there to represent us," he says. "We keep electing the same congressman over and over and over again, and you can't really ever expect a different result. I believe our country could be heading on a better path."

Voters will decide who gets the job on Nov. 4.
