Martin O'Malley, the former Maryland governor and 2016 presidential candidate, is all-in for Beto O'Rourke in 2020, even though O'Rourke has not decided on whether to mount a presidential run himself. "I am really hoping Beto O'Rourke runs," O'Malley told Cheddar's J.D. Durkin Thursday, calling the former Texas congressman "fearless" and able to articulate progressive values "to the broadest number of people."
