In Montana, dark money helped Democrats hold a key senate seat

In the waning days of Montana’s hotly contested Senate race, a small outfit called Montana Hunters and Anglers, launched by liberal activists, tried something drastic. It didn’t buy ads supporting the incumbent Democrat, Sen. Jon Tester. Instead, it put up radio and TV commercials that urged voters to choose the third-party candidate, libertarian Dan Cox, describing Cox as the “real conservative” or the “true conservative.” Where did the group’s money come from? Nobody knows.
