How Dark Money Tipped Montana’s Senate Race

ProPublica reports a small “dark money” group called Montana Hunters and Anglers, launched by liberal activists, bought radio and television ads in Montana’s U.S. Senate race — not supporting incumbent Sen. Jon Tester (D-MT) but instead backing libertarian Dan Cox, describing him as the “real conservative” or the “true conservative.”

“Where did the group’s money come from? Nobody knows.”
