Incumbent Republican Senator Kay Bailey Hutchison had co-sponsored legislation supporting a constitutional amendment that would contain senatorial term limits, but stated that she would only leave office after two terms if such limits applied to all senators. After deciding not to challenge Governor Rick Perry in a Republican gubernatorial primary, Hutchison sought re-election to the Senate for a third full term.
