This is the part I thought was important:
"I'm also troubled by, not what Sen. McCain says, but what members of the party say, and it is permitted to be said such things as: "Well, you know that Mr. Obama is a Muslim." Well, the correct answer is: he is not a Muslim. He's a Christian. He's always been a Christian. "But the really right answer is: What if he is? Is there something wrong with being a Muslim in this country? The answer is: No, that's not America. Is there something wrong with some 7-year-old Muslim-American kid believing he or she can be president?"Someone had to say it.
I pretty much consider Colin Powell to be a war criminal. But this is the most moving and effective take-down I've seen of the McCain campaign's ugliness in recent times.
