I stand cynical to his ideals and sceptical of his abilities.
The reason why he got elected is because his opponent had severe disadvantages: political ties with what the world see as an incompetent ex-president, wrong choice of candidacy for vice president, and a dramatic show of an almost no-show for the presidential debate, a tactical move which failed him.
Obama on the other hand had little pressure on him. He's the "little known", with faults of his own that has yet to be seen. He managed to play down expectations of him to create immediate change, hence right now the mentality is more of giving "Change" a chance. He's being cushioned by a more forgiving US and international scrutiny.
I can't say that I like him, but he has yet to do something I dislike, so for now I wish him all the best.
