We're seeing the evil flowering of Jackboot Liberalism. You can already look up the term in Google, it's been around. It's the bared teeth, the ham-fisted thuggery that vandalizes campaign headquarters, rips up BC04 signs and assaults Republicans who get in the way.
Could someone please explain to me how this is any different than 60 Minutes "featuring" every anti-Bush book that's been published this year?
