Libertarian Eric Sundwall of Niverville is off the ballot in Tuesday's special election.
The state Board of Elections commissioners voted today to accept a report from board staff hearing officers invalidating more than half of Sundwall's petition signatures.
With those 3,786 signatures declared invalid, Sundwall has only 2,944 signatures. He needed 3,500 names to stay on the ballot.
Commissioners acknowledged that most of the signatures were ruled invalid because signers wrote the town where they receive mail rather than the town where they vote.
That state election law technicality has aggravated petition collectors for years.
Sundwall is in Poughkeepsie today responding to a complaint before the state Supreme Court. Three people, including the Dutchess County Conservative Party chairwoman, brought a complaint against Sundwall about his petition signatures.
