NORWAY, Maine — As Wednesday’s flash rainstorm lashed the windows of the 290 Maine Street pub, state Sen. Rick Bennett was holding court.The Republican from Oxford County sat with Carol Howard and Linda DuBois, a Republican from New Gloucester and a Democrat from Hampden, respectively. They were not constituents, but opponents of Central Maine Power’s transmission corridor project who wanted to meet Bennett in person. They wanted to know why Bennett, a top CMP critic, had introduced a joint resolution on the final day of the session declaring the Legislature felt the corridor constituted a “substantial alteration” of public lands.
