Why He's Rooting for John McCain : the guy makes a pretty good case; but, as someone said in the comments the lot for the Republicans could be to "sit in the corner and think about what they have done" for (at least) the next 4 years.
Obama, Huckabee sweep to Iowa victories : They each seem to have pretty slick political machines. This is what is needed to become President these days, especially as people are generally too mentally lazy to discern beyond the PR to real issues and to real potential. So while Ron Paul is the first and only true and consistent libertarian presidential candidate, he seems to have hurt himself by coming across as an "America blamer". Will it then be a Obama/Huckabee horse race in November ? We will see.
UPDATE : Libertarian or not, there is simply no excuse for racism. I am withdrawing my personal support for Ron Paul : right ideas, but the wrong man.
