Colorado's governor opposed marijuana legalization. But it's going so well, he's changing

Colorado Gov. John Hickenlooper (D) opposed the campaign to legalize marijuana in his state. But in a recent interview with CNN's Cristina Alesci, Hickenlooper seems to have warmed up to legalization after seeing its successful first year in Colorado, which was one of the first two states to legalize pot through a ballot initiative in 2012.

"It hasn't been the economic miracle, the economic sensation that people thought it was going to be," Hickenlooper said. "But at the same time, it hasn't been the nightmare that a lot of us skeptics and critics thought it would be."
