Who was the greatest President?

Alright who was the greatest, many people, myself included have said that Ronald Reagan was the greatest of all time but with this poll, lots of research and about 42 more hubs i'm going to try and find out just exactly who was the greatest, was it "father of his country" George Washington, was it the first republican Abraham Lincoln, perhaps wartime leader Franklin D. Roosevelt how about JFK the man possibly assasinated by his own goverment was it the bold moving, scheming, underhanded Tricky Dicky Nixon or could it be indeed the man who saw an end to the USSR, who survived an assasination attempt and who had one of the greatest personalities ever to enter the white house Ronald Reagan, well dont wait for me to start hubbing bio's of these 42 Historical Icons start voting

(Please note Barack Obama is not included because he is the current president but come back in 2012 and who knows)
