People are upset because people are impatient. I don't know how anyone can expect Obama to step into the White House, snap his fingers, and fulfill all the stuff he promised during his campaign. We've become a fast-paced society that demands instant gratification in all aspects of our lives. Sorry, there's no iphone app for making our government better.
I may have mentioned it here or some other forum, but I predicted that Obama would spend at least the first 2 years of his term undoing/dealing with all the bullshit from GWB's term. Then maybe, just maybe, he can start working on his campaign promises. But with the way things are going right now, I doubt it. And since people are so impatient, I doubt he'll get re-elected.
