I kind of doubt that. He started the Daily Caller in 2010 that is about as far right as it gets and sold off his shares a few years ago for a ton of money. The dude also comes from a ton of money.It's entirely possible but his career was floundering at the time he entered Fox. Once you enter that evening entertainment slot everything becomes fast and loose in the name of ratings. This is also the case with CNN and likely MSNBC.
But I guess I wouldn't know.
