Leland Lakvitz, also a member of the Saratoga Peace Alliance, held a sign that read, "Fund education, not war." He said he had mixed feelings about Gillibrand.
"She's a lot better than we had before," Lakvitz said. "But we're holding her to account. War is a moral issue."
Gillibrand said that Democrats tried to get stronger legislation passed.
"Two separate pieces of legislation focused on creating timelines to re-deploy our troops within the next several months and to begin to have accountability over the Iraqi people and the administration," Gillibrand said. "That was a solid piece of legislation that Congress gave to this president, and he decided to veto it."
Peace groups and Republicans are not the only political threats Gillibrand will face in her re-election bid next year.
Last week, Morris Guller, a liberal activist who ran for the U.S. House in 2004 as an Independent before dropping out and endorsing the Democrats' nomination, announced that he planned to oppose Gillibrand in a 2008 primary.
"I represent everyone in this district so it is important for me to listen first and foremost to hear what the folks in our district want done in Washington," Gillibrand said in a recent interview.
Gillibrand is a member of the Blue Dog Coalition, a group of 43 conservative and moderate Democrats in the U.S. House.
Gillibrand told the voters at the town hall forum she respected their opinions on the war.
"As a member on the Armed Services Committee, I feel a duty to those troops on the ground," she said. "I know many people disagree, and I respect your disagreement.""
