U.S. senators are increasingly looking to leave Washington for leadership roles in their home states. Amy Klobuchar of Minnesota joins Michael Bennet of Colorado, Marsha Blackburn of Tennessee and Tommy Tuberville of Alabama in running for governor. This trend highlights a shift in political ambition away from the Senate, which has become mired in dysfunction. Governorships offer the chance to govern effectively and build a national profile. The Senate is seeing the highest rate of turnover in more than a decade. Political historian Matt Dallek notes state-level governance is seen as more effective and appealing.
