I hope Bush knows what he's doing here...

According to this AP story, the President is going to announce Stephen Friedman as his top economic advisor this afternoon.

This line from the story is what most worries me: "Snow is likely to join Friedman in challenging tax cuts that threaten to put the government on course to long-running deficits, just as O'Neill did."

Can someone remind me again why O'Neill was dismissed? Wasn't one reason said to be that he wasn't supporting Bush's tax-cut based economic vision strongly enough? So how are Snow and Friedman different, exactly?
