Who were the best (and worst) presidents in U. S. History?

I just took this poll 20 Sep 2008 and looking back to see Bush was unpopular then as he is now and he still won the election. We also see how accurate these polls are. I am doing a poll for this election and it seems that there are more conservatives on line now then four years ago.
This is a good and interesting poll. It is also amazing that the most popular presidents are the ones the expanded government power the most. It is also amazing how many presidents we know nothing about. I tend to like the presidents that have done the least with government. I choose Chester Aurthor because he is completely forgotten so that means he probably did not do too much.
