As for Perry, I believe most "thinking" conservatives don't care much for him. He is similar to Bush 2 but not as smart, not as compassionate, more strident and unyielding in his positions. He does not know how to translate politics into policy -- much of his legislation has been more harmful than helpful and ususally revolves around some benefit to his supporters.
I believe most folks would honestly say the Texas economy has thrived in spite of Rick Perry rather than because of Rick Perry and there are some underlying problems in our economy that will arise in the long run based on the leadership he has provided.
I believe Bush 2 for the most part tried to do the right thing for the common good whereas Perry just does what is good for Perry and his friends. Perry's leadership the past several years has been in pursuit of his political ambitions, not what's best for Texas.
Perry claims to be a Christian, but best I can tell that's just part of his political persona.
Perry has never lost an election and he slings a lot of mud. He has a slew of wealthy and powerful backers so not sure I would count him out just yet.
