BRUNSWICK, Maine — One of the four independent candidates in the U.S. Senate race is shunning campaign contributions.

Danny Dalton of Brunswick said that while collecting signatures to appear on the November ballot from January to May, voters expressed concern over the influence of special interest groups, lobbyists and other campaign donors.

He announced Thursday that he won’t be accepting any campaign donations, so constituents can be assured that he would be “representing everyone equally.”

Dalton is a former federal worker who wants to cut down on federal waste.

He’s also a small business owner.

His announcement came a day after another independent, former Gov. Angus King, asked candidates to work together to limit expenditures by outside organizations — so-called super PACs — on behalf of candidates.
