I would have bet my overcoat that U.S. Senators have a residency requirement of nine consecutive years in the state in which they were seeking office. Isn't this true?
Great, we could use an overcoat to add to our collection!
According to the U.S. Constitution, Article I, Section 3, there are only three qualifications that Senators must meet.
Age 30 or older
A citizen of the United States for nine years
When elected, an inhabitant of the state they are to represent.
