(CNN) - Dick Cheney is weighing in on the Republican intra-party battle in Texas
The former vice president teams up with Sen. Kay Bailey Hutchinson at Houston's Hobby Airport Tuesday afternoon to officially endorse her bid for Texas governor.
Hutchinson is challenging two-term incumbent Rick Perry in next year's Republican Party primary. Perry has already won a re-election nod from the person who had hoped to succeed Cheney, Sarah Palin - last year's GOP vice presidential nominee.
While Cheney's favorable ratings among all Americans remain low, he's still well liked by conservative voters, who are crucial in a Republican primary battle.
Last week Hutchinson, who previously said she would resign her senate seat to run for governor, announced she will remain in the Senate as she seeks the gubernatorial nomination.
