John Sununu's appearance on Piers Morgan Tonight took an ugly turn when the normally unflappable Romney surrogate John Sununu said that Colin Powell only endorsed Barack Obama because they're both black. 

It was Sununu's last question of the night. Just before sending Sununu off, Morgan asked him if he thinks card-carrying Republican Colin Powell should leave the Republican party after he endorsed Obama for the second time in a row. "Frankly, when you take a look at Colin Powell, you have to look at whether that's an endorsement based on issues or he's got a slightly different reason for endorsing President Obama," he said. 

When Morgan asked what he was referring to, Sununu didn't hold anything back. "Well, I think when you have somebody of your own race that you're proud of being President of the United States, I applaud Colin for standing with him." 

For the record: Colin Powell cited Romney's "fluid foreign policy;" Obama's views on health care reform and the auto bailout; and said he was more comfortable with Obama on immigration, education and climate change.
