State: Colorado
Age: 54
Claims to fame: He went from superintendent of Denver Public Schools to the U.S. Senate never having previously run for political office and is viewed as an issue-oriented pragmatist who got elected in a swing state.
Biggest weaknesses: Political experts say his pragmatic platform doesn't have a natural constituency and he has a lower profile than the other six senators in the race.
Miami moment: He criticized Bernie Sanders' Medicare for All plan by arguing a public health insurance option is a better way to progress toward universal health coverage.
Candidate visits to Michigan: None.
