CHRIS MATTHEWS: It was a great speech. I thought it was a case in which the president of the United States didn't just speak at the U.N. but to the U.N. He was talking to the members of the U.N. Some was good politics making the connection with his grandmother coming from 100 miles away from Nairobi. Talking about the mea culpa of America not being a perfect country. We should have been better on public health in the third world, especially a reference implicitly to Ebola. Making a clear point that he's not against Islam.
