A series of closely watched primaries across the Upper Midwest delivered key victories for the Democratic Party’s progressive wing Tuesday night — with one major test still hanging in the balance in battleground Wisconsin. Flanagan defeated Rep. Angie Craig in a closely watched clash between the party’s progressive and establishment wings. Omar’s win adds to a string of primary victories for the congresswoman, who has previously survived well-funded efforts to oust her. Hong, a 37-year-old former chef and single mother, has drawn backing from nationally known progressives, including Reps. Omar and Ro Khanna of California. With most of Tuesday’s marquee contests decided, Wisconsin stands as the night’s biggest remaining test of whether the progressive left can carry its momentum into one of the nation’s premier battleground states.
