SARATOGA SPRINGS—After eight weeks, millions of dollars and countless hours of lost sleep, Jim Tedisco could not, on election night, give a speech declaring victory in his congressional bid. Instead, he did what he knows how to do: he vowed to fight on. In his 30-year career in elected office, this is the toughest election the Assembly minority leader has faced. He is, in theory, close to victory: there are about 10,000 outstanding absentee ballots and his opponent, Democratic businessman Scott Murphy, leads by about 60 votes. Given the district’s significant Republican tilt, Republicans say they are confident they will prevail when all is said and done.
