Regarding the general notion of consistency of political positions over time, McCain said in June 2008: “My principles and my practice and my voting record are very clear. Not only from 2000 but 1998 and 1992 and 1986. And you know, it’s kind of a favorite tactical ploy now that opponents use, of saying the person has changed. Look, none of my principles or values have changed. Have I changed position on some specific issues because of changed circumstances? I would hope so! I would hope so!” It is often reported that McCain has grown more conservative throughout his tenure in the Senate, according to various studies.
