From the article:

"Real change is never easy and the presidents who have wrought it have usually been a little ahead of the people, from Abraham Lincoln with the Emancipation Proclamation to L.B.J. on civil rights. Once again, Barack Obama has proved his conservative and liberal doubters wrong. He is now part of a very small club."

I agree with Mr. Purdum; President Obama is several steps ahead of us & it's a good thing, it's what a true leader must have and only a thinker can do.
President Obama Thank You!
