U.S. Sen. Kay Bailey Hutchison is again calling for term limits for the governor's office.
The Republican who's running against Rick Perry -- the longest-serving governor in Texas history -- discussed term limits in the first of four campaign stops Monday in Dallas.
Hutchison has for months been saying Perry's been in power too long and that the state needs term limits for the office, and said she'd seek a constitutional amendment to limit the top state spot to two terms.
Perry will seek an unprecedented third term in a re-election bid that starts with the GOP primary election March 2.

Perry spokesman, Mark Miner, says Hutchison has "no credibility on the issue" because she's been in Washington for 17 years after saying she'd serve two terms.
