You'll get different answers from different people, all dependent on their particular political point of view. My best suggestion would be for you to tune in and watch him for a week or two, decide for yourself.
I've caught his show on occasion, but don't see why he has everyone in an uproar? Most of what he says you can find elsewhere via Google News, with a less-dramatic spin.
I'm trying to understand what it is about him that polarizes people.
You are kidding of course. You of course know why everyone is talking about him...(but I am sure his audience is not growing, he already had a huge bunch of Fox idiots watching. His base is not growing.)
He called the president a racist. 46 sponsors didn't agree and pulled their advertisements from his show. The problem is, they didn't leave Fox so Beck will be fine eventually.
