“I’m running for president because we need dreamers in Washington, but we also need to get things done,” Hickenlooper, 67, said in a video announcing his campaign . “I’ve proven again and again I can bring people together to produce the progressive change Washington has failed to deliver.”

He becomes the second governor to enter the sprawling field, after Washington Gov. Jay Inslee announced last week, and is trying to cast himself as a pragmatist who can also take on President Donald Trump. Though as governor Hickenlooper prided himself for staying above partisan fights, he has argued his record as a former governor and big-city mayor distinguishes him from a broad field of Democratic presidential aspirants who are backing ambitious liberal plans on health care, taxes and the climate.

Hickenlooper has hedged on supporting Democratic rallying cries like Medicare for All and the Green New Deal to combat climate change. He once worked as a geologist for a petroleum company and was roundly criticized for telling a congressional panel he drank fracking fluid while arguing for the safety of the energy extraction technique.
