I answered you with sarcasm. Did you not get that?
The implication in your question (that Perry is a conservative) is flawed. Rick Perry is not a conservative, by any conservative's definition of the word.
Now, are there major politicians who are more conservative than Perry? Sure there are. Lots of them. Some are even running for president, or are contemplating it.
While there is no implication in that question anymore than there is in asking who is more conservative than Dennis Kukinich, tell me some of these acceptable to you.
Since I couldn’t see the sneer on your face I missed any attempt at sarcasm, grimace harder next time.
