Who would you say was the best president if merit were considered solely on the first lady"s accomplishments?

I would give that honor to Dolly Madison. During the War of 1812 she saved the portrait of George Washington when the British burned the White House. I wonder how many others would have the courage to do that. Another outstanding first lady would be Eleanor Roosevelt who was the eyes and ears of her husband as well as an ambador accross the nation and around the world.
