The district's second biggest voter turnout was in Jefferson County, where Hoffman also has benefited from a turnaround since election night, gaining about 700 votes. Owens led Hoffman by 300 votes on the final election night tally. But after recanvassing, Hoffman now leads by 424 votes, 10,884 to 10,460.
Jerry Eaton, the Republican elections commissioner for Jefferson County, said inspectors found a problem in four districts where Hoffman's vote total was mistakenly entered as zero.
"Hoffman definitely gained votes where he didn't have them," Eaton said.
Jefferson County, home of Fort Drum and the Army's 10th Mountain Division, distributed 2,299 absentee ballots for the special election. As of this week, 1,303 had been returned but not counted, Eaton said. He said the county will begin counting the absentee ballots earyl next week.
Conklin, of the state Board of Elections, said officials did not have updated absentee ballot totals from the other counties.
When asked about the tightening race, Owens spokesman Jon Boughtin released a statement without directly addressing the election. "Since being elected, Congressman Owens has remained focused on the issues at hand: working with local leaders to address the Champlain Bridge closure, meeting with commanders at Fort Drum and continuing the work to strengthen Upstate New York," the statement said.
Ryan said the absentee ballots are likely to favor Hoffman because most were likely mailed before Republican Dede Scozzafava suspended her campaign three days before the election.
"For Doug to win, we needed a three-way race," Ryan said, adding that the campaign's internal polls showed Hoffman would win with all three candidates.
"Given the majority of these ballots are from a three-way race, we think the ballots are going to break Doug's way," Ryan said.
Ryan declined to say what percentage of the absentee vote the campaign believes Hoffman would need to win the race. Nevertheless, Hoffman's campaign is optimistic.
"When people look back at this race, it was a remote possibility that Doug Hoffman would be a contender," Ryan said. "But miracles do happen.
