Troy Jackson stood alongside a small group of loggers deep in the northern Maine woods and stared down State Police troopers who threatened to arrest them. That moment set the fifth-generation lumberjack on a path into politics, eventually making him Maine's unlikely Democratic nominee for U.S. Senate. "What I am is a guy from northern Maine that’s a logger," Jackson said. He has butted heads with both Republican and Democratic lawmakers while in the Legislature, including Democratic Gov. Hafford, who worked alongside Jackson as a logger, has seen that fiery side but chalked it up to strong feelings.
