yeah, but many on DU are self-proclaimed libs. They tend to be a tad dramatic, just as many on the far-right are. You're just as likely to hear "those who refuse to work DESERVE FREE EDUCATION!" from the far left, as you are "OBAMA IS A KENYAN HERE TO DESTORY OUR VALUES!" from a far-right guy.
In other words, the far left are drama queens. They'll vote obama in 2012 because they'll get all worked up over whoever the GOp sends out. They wont show in 2010 tho.
