Hillary Clinton's "got work to do" following her loss Tuesday night to Vermont Senator Bernie Sanders in the New Hampshire primary, said her supporter Congressman Stephen Lynch.

"It's going to be a long process," he said. "I think this is a marathon and not a sprint. I still like our chances."

Sanders triumphed over Clinton by a huge margin, winning 60% of the vote to her 38%. It was the second widest margin in a Democratic New Hampshire primary race in history, coming in only after John F. Kennedy's win over political novice and "Space Pen" inventor Paul Fisher in 1960.

Lynch said he still believed Clinton would win the nomination.

"She's very well-organized," he said. "Bernie obviously had a great following in New Hampshire but I don't think that's necessarily reflective of the entire Democratic Party across the country. I'm optimistic. I think she'll do well, I think she'll be our eventual nominee, but she's got work to do."

Lynch said, however, he believed Sanders' success had improved the quality of discourse on the left overall.

"I give Bernie credit for raising some of the issues he has raised," Lynch said. "He's elevated the quality of the debate."
