From Eric Dondero:

In 2009, Texas Governor Rick Perry was the featured speaker at a Tea Party event outside the State Capitol in Austin. He made his now famous remark that "Texas had the right to secede," if the federal government overstepped its bounds.

Appearing on CNN a few days later, Texas Congressman Ron Paul was asked about Perry's remarks.

Via the Manchester Union-Leader, Aug. 18:

[Paul called Perry's comments] “very much American.”

“We seceded from England, so it's a very good principle,” Paul said on CNN in 2009. “It's a principle of a free society. It's a shame we don't have it anymore. I argue that if you had the principle of secession, our federal government wouldn't be as intrusive into state affairs, that would be very good.”

Paul was also quoted recently on him entering the race, that Perry's free market views made him "look like a moderate."
