Archaeologists have recently discovered the remains of the first liberal socialist. If you look closely, you can see that current liberals (like Kevin Lynn and Steve Corbett) and early liberals are virtually identical. Notice the head's position lodged firmly in the ass. Why there have been no evolutionary changes remains unclear. Scientists speculate that this head in ass posture ensures that the liberal truly comes to believe that his shit doesn't stink. I will keep you updated as new information becomes available.
