I wonder where they meet these people.  Seriously.  I know lots of people.  I know ones that were voting democrat.  I know ones that weren't voting.  I know ones that were voting republican.
I know democrats that have been turned off by Barry, and won't vote for him.  I know some democrats that like McCain and are voting for him.  I know some that weren't voting and now are, the usual reason seems to be to vote for Sarah Palin.  I know some Republicans that don't like either ticket and aren't voting.  
I don't know of a single Republican that has decided to vote for Obama.  No doubt some do exist, but I don't know of any.  Weird that.
