Kansas Governor Sam Brownback will endorse Rick Perry on Thursday, according to Perry aides. He will then attend the GOP debate in Florida, as Perry’s guest.
Brownback, who also ran for president in 2008 and served in the U.S. senate, now becomes the third governor to endorse Perry — joining Louisiana Governor Bobby Jindal and Nevada Governor Brian Sandoval.
The endorsement is not a complete surprise. Brownback attended Perry’s prayer rally, “The Response,” at Reliant Stadium in Houston in August.
In the U.S. senate, Brownback, who is a Catholic convert, championed social conservative causes, including working to end human trafficking and defending the right to life. He is considered a hero of the social conservative movement.
Earlier this year, Brownback’s former chief of staff and presidential campaign manager endorsed Jon Huntsman for president.
