Of the early states, SC is open, so look for 'Operation Chaos'-like shenanigans there. Hate to say this, but that may put Yeb over the top in SC.
I worry about SC too...they RATS and pubbies actually vote on different days Im told.....
They will still cross over by changing their registration for the primary. They did that last time because by the time Super Tuesday rolled around the Democrats already knew they had their candidate Hussein. They did not need to vote in the Democrat primary. Bush is counting on the Temporary Republican vote.
