I liked bill o'reilly a great deal when his show first appeared. but when he hit it big in the ratings, he became unbearable. he can't go 5 minutes without talking about himself, and he relates every issue, discussion, and segment back to him. it truly is all about him.
and I'm not sure he is a conservative. his "looking out for the folks" shtick, aside from patronizing and annoying, comes off as oddly populist. I don't think there is such a thing as a populist conservative. I think you would just call that person "confused".
I used to not mind watching Bill. I even went to an event where he was speaking in Dallas and got a book autographed. Then it was about a year or so later I completely stopped watching him.
Edited to add: This was pre-2004 Presidential election.
