Tina Smith pledges neutrality while praising Flanagan

Endorsing Minnesota Lt. Gov. Peggy Flanagan over Rep. Angie Craig (D-Minn.) in the state’s Senate Democratic primary is quickly turning into a progressive litmus test.

In recent months, Flanagan has received the backing of Sens. Bernie Sanders (I-Vt.) and Elizabeth Warren (D-Mass.). On Thursday, Democratic Sens. Chris Murphy (Conn.), Chris Van Hollen (Md.), Jeff Merkley (Ore.) and Martin Heinrich (N.M.) also endorsed Flanagan.
