The Latest: Darline Graham, Ralph Norman advance to GOP runoff to replace late Sen. Lindsey Graham

Primary elections are taking place in six U.S. states — Alabama, Connecticut, Minnesota, South Carolina, Vermont and Wisconsin. Minnesota voters will settle a moderate-versus-progressive Democratic U.S. Senate primary on Tuesday between centrist U.S. Rep. Angie Craig and progressive Lt. Gov. Peggy Flanagan. In the race for governor, Mike Lindell, known as the MyPillow Guy, leads a crowded Republican primary with President Donald Trump’s endorsement, while Sen. Amy Klobuchar faces minimal opposition for the Democratic nomination. Wisconsin's Democratic primary for governor is another high-profile clash between the party’s establishment and progressive wings, as democratic socialist Francesca Hong tries to rise above establishment candidate David Crowley.
