I think glimpses of real personality can be had into the likes of Limbaugh, O'Reilly, and Beck. I'm not so sure about Hannity. But they are not to be confused with actual human beings. They are mouth pieces, they spew the rhetoric and that's it. If they did any more than that publicly they probably would lose a lot of viewers.
But also don't think I affiliate myself with the other side of the aisle either, that's false dichotomy. Just because I recognize how utterly ridiculous Hannity (usually) is doesn't mean I consider myself a democrat.
Though, I do find Bill Maher entertaining sometimes. Certainly a lot easier to watch/listen to than his counterparts. When I turn on the radio and listen to Hannity talking about a US invasion of Iran as if it's already a foredrawn conclusion, (for example) I feel an aneurysm coming on and have to cut it off.
