A compelling vision of caution.
The other night, though, I heard Obama say words to the effect of "we can change America".
That's a little different than claiming he or we can change the government of American and its policies.
In fact, beyond providing yet another item on the list of politically incorrect things to say or do if you really, really, truly, super duper, double triple true dat luv America more than anybody else, I'm not sure anyone can really change America. It's a rather diverse country, after all, and becoming more diverse all the time. Even Reagan in the age of Reagan didn't change America all that much.
