That touched off a symbiotic relationship. If Polis, and fellow public option supporter Rep. Chellie Pingree (D-ME) would work the inside game in the House, the groups would build pressure from the outside, and together they could build a formidable list of signatories to a letter.
"In about a week we got 118 people on the letter in the House," Green says.
To build on that success, the groups and members needed a parallel effort in the Senate. For that, Polis turned to his Colorado co-delegate, Sen. Michael Bennet.
