In the sound byte I heard he did not use the word dismissed - he said the person would be "taken care of". Certainly Rove has been "taken care of".
As for "promises" from politicians, they are broken by all of them, including the lefties. This perceived "broken promise" is just like any other.
This has nothing to do with what Carl Rove did, or what Bush promised, it's all about the same old incessant political attacks of the last four and half years by the losers who just can't seem to convince enough people to vote for them. This follows 8 years of the same but under a different party/administration.
