The difference is that Perry obsesses about Texas, too. On the campaign trail, he’s the ambassador from the Lone Star State, promoter of the Texas Miracle, filtering almost everything through a Texas prism. On his maiden voyage through the Iowa State Fair, some hecklers were giving him a hard time, the typical hazing for a new face on the national scene, and Perry’s response was instinctive.

“That may not be an Aggie over there,” he yelled, pointing at a heckler…

We have had several Texas presidents, but none so deeply, intensely Texas as this guy would be. (Walking on the stage with the other debate candidates, Perry is so much broader of chest and squarer of shoulder and straighter of spine than the rest of the pack that he looks as if he might have been stuffed.) Dwight Eisenhower, who was born in Texas, moved out before he was 2. Lyndon Johnson had long since become a man of Washington when he entered the White House, though he worried that Northerners would make fun of his twang — which they sort of did. George H. W. Bush was basically an Easterner who had moved to Texas for his job. His son was much more of a Texas product, but his parents sent W. off to boarding school to erase some of the evidence.

RICK PERRY has never spent any serious time outside of Texas, except for a five-year stint in the military. Nobody sent him off to boarding school to expand his horizons. He grew up in Paint Creek, where he graduated third in a high school class of 13. He went to the most deeply Texas of all the state’s major institutions of higher learning. He was a terrible student, but won the prized post of yell leader, the most deeply Texas of all possible Aggie achievements.
