First in war, first in peace, first in the hearts of his countrymen. There is no equal.
Runners up in my book include Ronald Reagan (for turning the tide in this country against the forces of despair domestically and tyranny overseas) and Theodore Roosevelt (for, one and for all, settling the question of who was in charge in the Americas).
Most overrated is FDR, a man who succeeded tremendously in appointing a war cabinet that defeated two major world powers, but was a total failure in terms of domestic policy (higher unemployment prior to WWII than when he took office, court packing, etc.).
I see The General in relation to our presidents in the same way I see Bach in relation to other composers: It was The General alone, then we can quibble about who came next and third and so forth. Same for JS Bach...
Agreed. Washington hands down.
