Can someone tell me what DU is?
The Democratic Underground, AKA the RATS underground, AKA the underground of RATS. These guys are the nuttiest of the nutty leftists. They want the war to go badly. They want the economy to tank. Basically, if their side isn't in charge, they want America to fail.
It's like PU. It's a website with people who don't often bathe. They find it too hard to get out of bed - ever. They have their Twinkies delivered to them by one of their 19 or so kids. No one can find the fathers.
They spend a lot of time looking at pretty Internet pictures, so they can stay politically informed.
