Obama’s senior adviser David Plouffe — who served as 2008 campaign manager then blended inside and outside assistance — is a model Conway has studied.

Responding to questions from The Hill, Conway described such an outside group as “potent and necessary.”

The group would combine advertising support, door knocking, and other grassroots activities to support Trump and his legislative agenda. It would play defense when necessary, push key pieces of legislation such as the ObamaCare repeal, and help in major fights such as the coming battle over the late Antonin Scalia’s Supreme Court vacancy.

Conway said it would be important to install someone in the leadership role “who has the trust of the president-elect, grassroots, donors, and Capitol Hill.”
