How many times may a Senator be re-elected?

A Senator may be re-elected an unlimited number of times. The U.S. Constitution does not impose any term limits on Senators, meaning that they can run for re-election as many times as they choose, provided they continue to win the support of their constituents. This flexibility allows experienced political leaders to remain in office for extended periods, as seen with several long-serving Senators throughout U.S. history. The absence of term limits encourages continuity in representation and can enable Senators to develop greater influence over time, running for re-election in a manner that reflects the democratic process and the will of the voters.
