AUGUSTA, Maine – A Washington County physician qualified for the November gubernatorial ballot on Friday, joining Gov. Janet Mills and former Gov. Paul LePage in the high-profile race.Sam Hunkler, a retired doctor from Beals, submitted more than 4,000 valid signatures to the secretary of state’s office on Friday, just a few days ahead of the deadline for unenrolled candidates. He is of a different mold than previous independent candidates for governor, who were often former lawmakers, such as Terry Hayes in 2018, or independently wealthy businessmen, such as Eliot Cutler in 2010 and 2014. Hunkler has promised his campaign will stand for a “different way of governance” and “finding common ground.” His website mentions issues such overhauling substance use disorder treatment, reforming property tax laws and creating living-wage jobs, although he is light on specifics, saying he would rather listen to others than press his stances on issues. He is self-funding the effort and not accepting campaign contributions, although he had only put $1,000 toward his campaign through April 26, according to filings with the state’s ethics regulator.
