SAN ANTONIO — Gov. Rick Perry was a champion of fiercely conservative social activism long before the tea party was born. He oversaw the “Texas Miracle” job-creation boom and became the state’s most powerful governor since Reconstruction.

But nationally, Perry is better known for his ‘oops’ presidential debate brain freeze or for not opposing forcefully enough the notion that Texas could secede from the union. For many outside the Lone Star State, he’s a political punchline on par with Dan Quayle — if he’s known at all.

Now, the longest-serving governor in Texas history is quitting his day job. Perry announced Monday that he won’t seek a fourth full term in office next year, but notably didn’t say whether another run for the White House in 2016 could be next.

“The time has come to pass on the mantle of leadership. Today I’m announcing I will not seek re-election as governor of Texas,” Perry said Monday. “I will spend the next 18 months working to create more jobs, opportunity and innovation. I will actively lead this great state. And I’ll also pray and reflect and work to determine my own future.”

But for that future to include another run for president, Perry will first need to concentrate on rebuilding his tattered image outside of Texas.

“He’s starting behind the eight ball,” said South Carolina-based Republican operative Hogan Gidley, an adviser to former Pennsylvania Sen. Rick Santorum and ex-Arkansas Gov. Mike Huckabee — both unsuccessful presidential hopefuls who have remained national conservative forces.

Perry had never lost an election during his 27-year political career.
