One of Schroon’s empty storefronts has a new tenant: David Mastrianni, an oncologist from Saratoga, who is running as one of nine Democrats for the 21st Congressional District.

Those Dems will duke it out to see who gets to take on Republican incumbent Elise Stefanik in November.

Mastrianni, a long time second homeowner in Schroon Lake, is the senior vice president of the Saratoga Hospital Medical Group.

His campaign headquarters are across from Stewarts. In a statement, Mastrianni cited health care, agriculture, infrastructure, education and the environment as leading campaign issues.

“At times, our federal government does not acknowledge the issues of rural or small-town areas such as our district, resulting in its failure to meet its responsibilities to our region,” Mastrianni said in a statement.

“Many federal policies favor large corporations and other interests over our people and our communities.”
