Creationist Republican candidate Rick Perry’s book “Fed Up” argues that nearly every federal social program is unconstitutional, and a month ago he was proudly signing copies and recommending that people read it.

But suddenly, since entering the Presidential race, Perry is disavowing the whole book: Rick Perry Is Less ‘Fed Up’ Over Social Security.

Texas Gov. Rick Perry used to be pretty frank when it came to the country’s Social Security system. In his fiery anti-Washington book, “Fed Up!”, published last fall when he had no plans to run for president, Mr. Perry called the program, which turned 76 on Monday, “a crumbling monument to the failure of the New Deal.”

He suggested the program’s creation violated the Constitution. The program was put in place, “at the expense of respect for the Constitution and limited government,” he wrote, comparing the program to a “bad disease” that has continued to spread. Instead of “a retirement system that is no longer set up like an illegal Ponzi scheme,” he wrote, he would prefer a system that “will allow individuals to own and control their own retirement.”

But since jumping into the 2012 GOP nomination race on Saturday, Mr. Perry has tempered his Social Security views. His communications director, Ray Sullivan, said Thursday that he had “never heard” the governor suggest the program was unconstitutional. Not only that, Mr. Sullivan said, but “Fed Up!” is not meant to reflect the governor’s current views on how to fix the program. …

In an interview, Mr. Sullivan acknowledged that many passages in Mr. Perry’s “Fed Up!” could dog his presidential campaign. The book, Mr. Sullivan said, “is a look back, not a path forward.” It was written “as a review and critique of 50 years of federal excesses, not in any way as a 2012 campaign blueprint or manifesto,” Mr. Sullivan said.
