Rachel Maddow hits all the right notes here. I highly recommend watching this.
I don't think it's easy for people outside the U.S. right now to properly gauge just how absolutely crazy the hardcore base of the conservative movement is acting right now. From their media stars (Limbaugh, Beck) to irresponsible politicians (Palin, Cheney) to nutjob foot-soldiers, they have all coalesced around the idea that Barack Obama is dangerous, is a Nazi, is a Socialist (anyone remotely familiar with European history will find those characterizations going hand in hand quite funny), and is a threat -- a physical threat -- that must be countered. Combined with racist misgivings about his race...I don't even want to put in words what I'm thinking. You know what I'm talking about.
