From "sayings and proverbs" which I received today:

Happy 227th Birthday America!

the Declaration of Independence, it would have been
worthwhile.
--Samuel Eliot Morison

The American dream is not over.
America is an adventure.
--Theodore White

America did not invent human rights. In a very real
sense, it is the other way around. Human rights
invented America.
--Jimmy Carter

nothing they can't lick.
--John Wayne

What the people want is very simple - they want an
America as good as its promise.
--Barbara Jordan
