We say "he claims" because that's what we know at this point. It's the second story in Wisconsin in less than a week where conservatives allege that they were severely beaten by liberals. The first was Sean Kedzie, son of State Senator Neal Kedzie, who says he was beaten by two men trying to take his Romney/Ryan sign from his yard.
It seems pretty clear Wood was attacked. If his story as to motive for the attack is true, this is a distrubing trend.
