Will you still vote for Obama if he doesn't define his version of "change"?

My main concern and complaint about Obama. I like him, but he better start getting specific pretty damn soon. How long can he run on the word "change" without talking about just what these big changes are, how he's going to effect those changes, etc. Doesn't anyone require specifics anymore or is it just enough, especially for our younger generation, to hear the word "change" and a non-specific inspirational sounding speech to elect a President? Yes, that is exactly what lemmings do. It's really sort of incredible.
