This is the first step.
Step 2: Biden vanishes from the campaign trail for ten days.
Step 3: Biden re-emerges to announce his doctors have discovered a previously-undisclosed medical condition that would make it impossible for him to serve as vice-president, and that he is stepping down.
Step 4: Obama introduces Hillary Clinton as his new running-mate.
Step 5: All the sheep women who flocked to McCain/Palin come back into the Democratic fold. Obama rides a new surge of support to victory in November.
Step 6: Obama found dead in the Oval Office of an apparent heart attack. Three lit cigarettes are found in his mouth, along with a full package's worth of chewed-up Nicorette gum, and six nicotine patches on his arms, another eight on his legs.
Step 7: As a stunned nation mourns, Hillary Rodham Clinton is sworn in as the 45th President of the United States of America. Her first official act: Names Joe Biden Chief Justice of the United States, replacing the recently-deceased John Roberts, who had been killed by a mysterious Chinese lone gunman (who then turned his gun on himself) just a week before.
