Kristen McDonald Rivet is in the news mainly because she is part of the competitive Michigan Democratic Senate primary ahead of the 2026 election. A recent poll of likely Democratic primary voters suggests broad appetite for new party leadership, which adds to the sense that the race is still taking shape. Michigan’s Senate contest is also drawing more attention as Republicans see a tougher environment and Mike Rogers attacks Democrats over the state’s economy and national party direction. Separately, reports note that a state Senate seat she vacated remains central to a special election that could affect control of the Michigan Senate.
