Former governor of Colorado

State: Colorado

Age: 67

Claims to fame: The former brewpub owner created a national model for regulating recreational marijuana, won in a swing state and was booed at the California Democratic Convention for saying "socialism is not the answer" to advance progressive goals.

Biggest weaknesses: He has an unconventional style, has joked he is too centrist to win the party's nomination and has been criticized for not regulating the energy industry more as governor. He shook up his campaign staff after the Miami debate.

Miami moment: He argued he brought Colorado closer to universal health care coverage without a huge increase in government like Bernie Sanders' Medicare for All. 

Candidate visits to Michigan: None
