Key primary races to watch in Michigan, Missouri, Kansas and more

Michigan Democrats on Tuesday will settle a Senate primary that has emerged as the most significant test of the party’s direction this year — one that will gauge whether the progressive insurgency that has toppled establishment figures and incumbents on deep blue turf all spring and summer extends into one of the nation’s biggest political battlegrounds. Progressive former public health official Abdul El-Sayed faces the more moderate Rep. Haley Stevens in the race to take on Republican former Rep. Mike Rogers. The race has implications that extend into 2028, offering prospective presidential candidates a glimpse at what the party’s electorate wants in Michigan, likely to be one of the first six states to vote in the Democratic nominating calendar and a must-win in the general election.
