Forget La Hill and Obamarama. For real mudslinging and general campaign ugliness, check out John "2003 All Over Again" McCain and Yosemite Mitt, who are calling each other...liberals. (Wonder what they think of Ron Paul.)
Ya know, as a lifelong liberal (not just progressive, but LIBERAL), I can assure you it's a perfectly normal state of mind. I think McCain and the Mittster have been visiting too many wingnut talk shows and CPAC conferences.
This is the GOP in 2008. Even their campaign slurs are stupid.
