Deep thoughts:

It is fascinating to me that the name "John McCain" lends itself to a more damaging moniker than the name "Barack Obama".  On its face, the name Barack Obama, Barack Hussein Obama no less, would seem to lend itself to a myriad of permutations of Saddam Hussein or Osama bin Laden or twenty other distinctly alien-sounding Middle Eastern names.  This should be tremendous baggage on Barack Obama.  But so far nothing seems to work.  Sure, all the right-wing blowhards emphasize his middle name.  But, really, that's going to get old, if it hasn't already.

But somehow the moniker "McSame" seems more damaging.  I personally don't care for it.  Nevertheless, it seems to capture the zeitgeist better.  People want change, they want George Bush to disappear from the face of the Earth for good.  Plus, the opening "Mc" gives it a certain low-rent cookie-cutter quality like "McMansion" or "McDonald's".  Yes, I know I am reading way too much into this.
