More Greenwald greatness in which he explains that if you are a shill for one party and get caught up in the game of wedge politics as you rant and carry on about the baddies on the other side of the aisle you essentially send the following message to "your" party.
"I'd really appreciate it if you did X, Y and Z, and strongly believe you should, but even if you don't, you should know that I'm going to be there for you and your party: cheering for you, raising money, demanding that everyone else support you, doing everything in my ability to keep you empowered."
And as it turns out, it's not your party after all. They just let you hang around to go get their beers for them but the second you object you are unwelcome nuisance.
This is just as applicable for the right as it is for the left. In fact, it is more applicable. In this recent presidential campaign Conservatives carried the water for a socially moderate, fiscally liberal North Eastern Republican in the tradition of Rockefeller and got beat by an unpopular incumbent in a down-economy during a prolonged war. Seriously. Think about that.
If ever there was a time for us to speak up it would be now.
