New York’s 19th Congressional District stretches from the wealthy enclaves of Rhinebeck and the tie-dye world of Woodstock across the Catskill Mountains to the struggling dairy farmers near Cooperstown. In this enormous district, seven Democrats are competing in the primary on June 26 to challenge Representative John Faso, a first-termer who is considered one of the most vulnerable Republicans in the House.

This impressive field has divided party loyalists and independents alike, and the energy of the campaign has been matched by the energy of residents. The eager involvement of mostly homemade, neighborhood political clubs, and lively attendance at campaign events, is a welcome change in the political scene. These enthusiasts are anxious to take each candidate’s measure in person. One contender estimated that there have been at least 50 candidate forums.

Here are the choices:

Jeff Beals, an intense former diplomat and C.I.A. officer, moved to the district to become a teacher at a private school in Woodstock. Mr. Beals has promised to “fight corporate power” and calls Senator Bernie Sanders an inspiration.

David Clegg, a lawyer and ordained Methodist deacon, has lived in the district for 37 years and is well known for his public service as a basketball coach, a volunteer for Habitat for Humanity and in fights against corporate polluters.
