CHRIS MATTHEWS: At least back in 1939 when Marian Anderson had to sing here "My Country, 'Tis of Thee" rather than at the Constitution Hall because they said the reason was she was black. At least they were honest back then. Today in American politics you have people like Donald Trump who hangs around with Mitt Romney talking about the president being an illegal immigrant, basically being a con artist on the street corner. You've got people talking about nullification of the law of the land. You got people talking impeachment like Coburn. You've got Ted Cruz out there. They never say their problem with Obama is that he is black, but look at the pattern. The pattern is rejection of his legitimacy at the first point, saying he is not really here legally. It's rejection of the law he has passed, the landmark bill passed in 2010. Itâ€™s an attempt to impeach him on no grounds. At least the Daughters of the American Revolution knew what they were saying, and they said it out loud. He's black. Sheâ€™s black, she can't sing here. These guys today use all of the techniques of nullification and talking about illegitimacy and accusing the president of being a crook basically for even being president because he's here illegally. And then they talk about impeaching him on grounds they can't even come up with. At least in the old days they were honest about it. Today, they're not. And thatâ€™s how rough it's going to be today, I think.
