|"not simply change for the sake of being different."|
I don't think anyone running, on the republican or democrat side, is just running for change for changes sake. I am sure they all believe their program is a change (and they are all more or less correct), and they all believe in the justice of their positions, and the rightness of their path. If people didn't believe that, they wouldn't choose the path they are on.
I think the entire crop of politicians this time around is pretty interesting, and I think they all have a commitment to one set of ideals or another. I know some people think only "their" candidate (whoever that is) has such a commitment, but I think that's a strangely shortsighted view.
