Who said 'You can fool all the people some of the time and some of the people all the time but you cannot fool all the people all the time?

The quote is, "You may fool all the people some of the time; you can even fool some of the people all the time; but you can't fool all of the people all the time." Roy P. Basler attributes this to Abraham Lincoln, from his 2 September 1858 Clinton, Illinois speeches.
