Carlo sits down with Sen. Michael Bennet of Colorado for a discussion about his uphill presidential campaign. You may not be familiar with Bennet, but he has one of the most ambitious policy agendas of all the Democrats running in 2020. Bennet outlines his approach to taking on President Trump and why he eschews the label "centrist" for a title he says better describes himself -- a "pragmatic idealist." First in a series of conversations with the 2020 candidates.
