Perry has trouble listing anything, and until he can get his message down, there is no worries about him. Those public gaffes of him trying to list off two or three things will keep him a clown in the eyes of voters. He did it with his agencies, and did it again in the last debate.. two options, no choices, wait, three actually.. ok, well, just two.
He has money, a good message, but he is no where near polished enough to be taken seriously. Nobody wants to hear that bickering on stage either. A huge turn off for people, they see it as more of the same.
