Elissa Slotkin had less than half an hour to reckon with a retirement announcement that would reshape Michigan’s political landscape. The state’s senior senator and the third-ranking Democrat in the chamber, Debbie Stabenow, was about to reveal that she would retire in 2024.

Rep. Slotkin, a Democratic congresswoman from Holly, soon met with her team to mobilize for a run at a U.S. Senate seat that Democrats had not expected would be hard to defend in the narrowly divided chamber. A powerhouse fundraiser who had won in one of the nation’s most contested House districts, Slotkin quickly emerged as the Democratic Party establishment’s top choice and began to set a torrid fundraising pace.

It took Michigan Republicans longer to find their frontrunner. Buffeted by turmoil between pro-Trump Republicans and the old guard of the state GOP, they eventually lured former U.S. Rep. Mike Rogers out of retirement to contend for the unexpected opening. The endorsement of former President Donald Trump gave Rogers a clear shot at winning his party’s primary without drowning in the intra-party conflict that has plagued the Michigan GOP in recent years.
