If his natty dress or the prodigious mustache didn’t impress you, former Montana lawmaker Duane Ankney’s understated sense of humor would. The longtime lawmaker, a former coal miner himself, died this weekend at 79. He was an unabashed champion of coal and his home district of Colstrip. He was a huge voice and advocate for the aging Colstrip power plant and mining for coal, understanding the economic engine of the southern Montana region. But in recent years, Ankney had also become more open to the idea of repurposing the Colstrip plant, converting it from coal to some other form of generation, including nuclear power.
