President Barack Obama :)

I think the greatest president of the U.S that we have had is Barack Obama because I like him and I think he has a clue with what he is doing. Just because hes made wrong decisions doesn't mean anything because everybody else has and no one is perfect. Plus the only other president I can remember is George W. Bush. I was to little to remember any other president, nor to pay attention to them because I was a little kid, I wanted to play with my toys, not watch tv about the president.
