I'm not a Democrat but Obama is clearly one of the most qualified to have ever become President.
What?
You could make the case about him being one of the "smartest" or something like that. You can say that he's shown himself to be more up to the job than others who were far more qualified....
But how is he one of the most qualified? He was only a US Senator for four years before being elected president.
What? According to that logic Strom Thurmond is more qualified than any president ever. What makes Obama one of the most qualified people to ever run is his education, his community work, his knowledge of the Constitution and his intelligence. Very few presidents if any have a resume as strong as OBama.
