Former Colorado Gov. John Hickenlooper said Monday that he will seek the Democratic nomination for president in 2020, becoming the first member of the crowded field to run by trumpeting a record of working with Republicans.

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

Mr. Hickenlooper, the 14th Democrat to formally launch a presidential campaign, is a former geologist turned brewpub owner who was mayor of Denver before being elected governor. He has spent recent months previewing his campaign in stops at pubs and breweries in Iowa and New Hampshire, hosts of the first nominating contests.

While most of the candidates preceding him into the race are defining themselves as progressives, Mr. Hickenlooper is the first of several candidates expected to join the contest from the party’s more centrist ranks. Unlike several of the other Democrats in the race, he hasn’t embraced a call for a single-payer health system. His campaign-launch video paints the 67-year-old as the architect of an urban renewal in Denver, as a two-term mayor of the city, and the steward of Colorado’s booming economy as a two-term governor.

The campaign video promotes his record as governor, which includes expanding access to health care, working with environmentalists and oil and gas companies to implement limits on methane emissions and enacting background checks on gun purchases and a ban on high-capacity ammunition magazines after the 2012 mass shooting that killed 12 people at a movie theater in the Denver suburb of Aurora.
