In an interesting opinion piece on [1] azcentral.com, the author writes:  “McCain’s persistence against the grain is drawing attention to yet another trap into which the GOP is flinging itself. He is warning his fellow Republican presidential candidates that their vitriol against illegal immigrants is getting wildly out of hand.”

In hindsight, McCain has been right on several issues.  I believe that he is also right  with his position on immigration, but apparently being right doesn’t get you elected.  Not taking a position or holding a moderate view on the issue will be the key to succeeding in the general election.
