These guys continue to show how little they think of Condoleeza Rice. To them, she is nothing more than a racial/sexual category. Sen. Robert Byrd is taking note of Rice's behavior, not her race and sex. The New York Times states, "Senator Byrd asserted that Ms. Rice had helped to make the Bush administration's case for an unconstitutional, unwise and unprovoked war against Iraq -- and had done so, he said, on the basis of faulty intelligence that she represented before the war as far more conclusive than it was. 'Accountability is not a negotiable commodity,' Mr. Byrd said, arguing that to confirm Ms. Rice would be to approve policies that had isolated the United States, made it more vulnerable to terrorism and cost American lives under false pretexts."
Byrd's critics don't seem to be up to defending Rice on the merits, so they are resorting to the Race Card.
I tried to find evidence of Byrd's position on the confirmation of Colin Powell in 2001, but the Senate doesn't list a roll call vote on the matter, leading me to believe that it was passed on a voice vote without objection. I would think that a klansman would be much more threatened by a black man.
UPDATE: Roger L. Simon: "But then I can't imagine having joined anything as wretched as the Klan, so maybe I would have ended up a self-righteous bloviator in the US Sentate. " You are a self-righteous bloviator. And Byrd is criticizing Rice's performance as the quote above shows.
