Within minutes of this audio, Rick Perry and Kay Bailey Hutchison supporters -- followed quickly by the press -- pronounced her campaign over. My understanding is that she has many supporters who are "Truthers" and she would not disavow any of them publicly -- hence her refusal to give a straight answer. An idiotic campaign move? Yes, absolutely.
But what's the difference between Medina having supporters who think the government was involved in September 11, and Rick Perry having supporters with signs that say this?
