If obama is a great president then I don't think that any major changes he will brings will really be seen until he is out of office (unless he has at least 2 terms)

He's got so much shit left over from the bush administration, got to pull out of Iraq without it crumbling like a jenga tower, got to fix the economy and deal with a lot of strained diplomatic relations (I see relations with other countries as taking the least time)

Even though these seeds have been planted years ago I'd hate to see Obama take the blame for things like the economy... shame it didn't come to a head a few months ago instead of as he's getting inaugurated
