I know a lot of people are attacking Obama's campaign slogans featuring change and empowerment, even though he doesn't provide many specifics.  People seem to be under the impression that if the empty shell is attacked enough, it will crumble as people realize that there are no specifics behind the slogans.  But keep this in mind:

"I many not know what tomorrow will bring, but I know I don't want more of yesterday."

If people hate the past enough, they will walk blindly into the future as long as it seems different.  Never underestimate the power in that idea.  Attacking "change for change sake" may not get you as far as you think.
