I've recently (over the past couple months since Obama won the Presidency), read more than a few blogs that have touted Obama as capable of superhuman and nearly god-like things. I'm, personally, sick of hearing this crap.
Obama is not some sort of superhero that will right all of the world's problems. He's just an intelligent man that can formulate a coherent sentence. He will likely improve a few things, worsen a few other things, and generally do the job a President is supposed to do - likely much better than his predecessor did.
The way I see it, the only reason Obama has become viewed as some sort of superhuman entity is because, for the past eight years, we've been subjected to a President that is a completely new caliber of idiot - to the point that even the common idiot thinks he's an idiot. Because of this, a simple education seems to have been elevated to an almost godlike status. I have news for you. Intelligence is not a superhuman power. It is simply the result of hard work and a desire to gain such an educational level.
Obama will not end the wars on terror and drugs. He might get us out of Iraq, but that's been in the works for at least a year now. He will not single-handedly end the financial crisis. If we see an end to the recession during his term, it'll be because of the work of the nation as a whole, not solely of Obama. He will not switch us to the metric system - I think he has far more important things to worry about. He may improve foreign relations - the rest of the world seems optimistic on this point.
I did not vote for him, nor do I support many of his proposed policies (or announced cabinet choices). He will become the President on January 20. I will give him the same chance I give any President. I will not make wild or impractical expectations of him. I will simply expect him to do his job to the best of his abilities.
Just keep in mind, Obama is not a deity. One would be a fool to think him such.
