Bush did pretty much the same thing, though admittedly he was only running for the presidency at the time and was not yet the president:
http://www.snopes.com/politics/bush/bushcuss.aspHe also did not apologize for it:
When directly asked about hsi remark, Mr. Bush responded, "I regret that a private comment I made to the vice-presidential candidate made it into the public airwaves," which was not an apology. when pressed as to whether he would apologize, he replied, "I was making a comment to... Cheney. I didn't realize, obviously, the mikes were going to pick it up"
Honestly I don't remember how big of a news story it was at the time though. I remember hearing about it but I'm not sure if it was a front page story for weeks.
Anyway, I don't have very strong feelings either way, I generally agree with jmizzle7 on this one. He obviously should never say it on record, but it is not really that terrible of a thing to have said. Then again I don't think what that senator did is very bad either, he at least knew his comments were public though. I may be somewhat biased because I think Kanye West is a jackass (we are talking about a man who hijacked a PBS fundraiser for Katrina victims by claiming the ridiculous statement "George Bush doesn't care about black people", among many other annoying attention seeking things he has done)
As to the hypocricy of the administration, I am not going to try to deny that but I also think that is a general behavior of each administration. I do see the news story on CBS and MSNBC though. ABC probably does not want to report it since it was their interview and was off the record, so it seems that would be against policy for them to quote it.
