PLATTSBURGH — Candidates for the 21st District congressional seat visited a number of local communities Friday as the final days of the campaign saw them set a frenetic pace around the district. Rep. Bill Owens, a Democrat, and businessman Matt Doheny, a Republican, are in a close race for the 21st District seat, polls show. The Green Party candidate, Donald Hassig, trails by a wide margin in the polls. Both Doheny and Owens said they intend to visit all 12 counties in the district before Tuesday's election. Doheny was in Plattsburgh on Friday, where he got the endorsement of Mayor Donald Kasprzak. "Matt embodies true North Country values; he’s worked hard to be successful," Kasprzak said in a statement. "As a candidate, he’s listened to my concerns as well as those of countless others and offered thoughtful ways he can make a positive difference in Washington." Owens was in Moriah on Friday, touring a business with Town Supervisor Tom Scozzafava, and heads to Malone and other stops Saturday.
