At one time he was a somewhat politically left, but mostly fairly balanced host of a decent show. I didn't always agree with him, but didn't mind watching from time-to-time.
But over the past year or two he's really sounded like someone that's gone a bit crazy. I don't know if it's because he's feeling pressure from declining ratings, or he just doesn't know what he thinks anymore and he's scrapping the bottom of his mental barrel for things to throw out there.
Chris Matthews is what happens when you back the wrong political horse, destroy your own career, lose your mind but still have a few years left on your multi-million dollar tv show host contract.
