I don't know how the Paul O'Neil book sold (I also love how those who refer to that book conveniently ignored how O'Neil went on TV the week after the book came out and denounced much of the tone, and said he was voting for Bush for re-election) but I would venture this will only appeal to the Hate-Bush core.
I happen to like CTW, but think she's just the latest in a line of Republicans who think moderate means "letting liberal values govern even though those same values lost at the ballot box". I'm waiting for someone like her to call on liberals to be more moderate.
