ST. PAUL, Minn. (AP) — Minnesotans are known for their niceness, but pleasantries are rare in the state’s Democratic U.S. Senate primary.

The two leading candidates, U.S. Rep. Angie Craig and Lt. Gov. Peggy Flanagan, have clashed over electability, their ties to corporate interests and willingness to fight Republican President Donald Trump’s administration in Washington. Millions of dollars in political ads have blanketed televisions and phone screens for a race that has become emblematic of Democrats’ deeper divides.
