Rep. Angie Craig and Lt. Gov. Peggy Flanagan are competing in the Democratic primary for the Minnesota Senate seat vacated by retiring Sen. Tina Smith. The primary occurs on Tuesday alongside House primaries, with polls closing at 9 p.m. EDT. Craig has received nearly $10 million in outside spending from groups with undisclosed donors, while Flanagan holds the Democratic-Farmer-Labor Party endorsement and support from Sens. Bernie Sanders and Elizabeth Warren.
