Tuesday primaries test Democratic drift from Wisconsin to Connecticut

Tuesday’s primaries in Wisconsin, Minnesota, South Carolina and Connecticut are framed as tests of the Democratic Party’s leftward shift and a push for generational change: Wisconsin’s governor race is led by Francesca Hong, a democratic socialist, in a chaotic field; Minnesota’s contests could reshape who rules the state’s Senate and its leadership, with Klobuchar likely to win the Senate nomination; South Carolina’s special Senate primary, buoyed by Trump’s backing, could go to a runoff; Connecticut centers on replacing veteran Rep. John Larson with new voices in a generational clash; and a separate Wisconsin 3rd District race pits a moderate against a progressive, with implications for November.
