When Monica Tranel corrected Ryan Zinke on the full name of the monopoly power utility in Montana, the audience broke the “no cheering” rule.

Zinke, the Republican and former congressman running for the U.S. House of Representatives, touted American energy as cleaner and better than foreign energy. He pointed to his opponent, “an environmental attorney” who has sued the power company, as to blame for “Northwest Energy” raising rates.

“To think you’re going to make Montana one giant windmill, and hydrogen is going to provide the power, is just simply nuts,” Zinke said.

“It’s NorthWestern Energy, which you would know if you lived here in Montana and paid bills to them,” Tranel said, stressing the “ern” in the name and eliciting the only clapping and cheering of the debate.
