Rick Perry prays at The Response, a call to prayer for a nation in crisis in Houston. During the prayer rally for thousands Perry read from the Bible, invoked Christ, and broadcast the whole event on the Web, without so much as a symbolic nod to other American faiths. It was a rare, full-on embrace of one religious tradition in the glare of a presidential contest. (AP Photo/David J. Phillip) The Associated PressAUSTIN, Texas (AP) — Rick Perry's presidential campaign has begun to distance itself from some of the explosive rhetoric in the Texas governor's book that came out just nine months ago.Its title is "Fed Up!" and the Republican politician doesn't hold back.He brands Social Security a failed New Deal experiment. He says states' rights should trump all else. He suggests that Congress should be able to overturn rulings from the Supreme Court's "oligarchs in robes."But Perry recently has pledged support for a constitutional amendment that would preclude a state's right to allow gay marriage. And his campaign no longer repeats his strongest words about Social Security.Republican political consultants say Perry's book could make it harder for him to win the support of elderly voters and conservatives concerned about his electability.
