Our big problem with politicians is and always has been that there has always been those who either don’t have a philosphy and those who live in districts where they could not get elected if they ran on what they believe. They will run under whatever banner they believe they can get elected under and say what they think will get them elected. I doubt Crist ever had Republican ideals much less any Conservative leanings. I believe we may have seen some of this in our Presidential nomination process.
They are all actors, who play their roles.
