Blue Turtle Shell Syndrome.
You will see when you watch the Republican Primary and when you play Mario Kart the key similarity is that if you get too far ahead then all the other players behind you will gang up on you and you will be destroyed thus being drawn pack into the pack. The key weapons against the leader is the blue turtle shell. The Blue turtle shell when fired by anyone from the rear of the pack will, invariably and without deviation seek out the leader and crush him or her. They will fly into the air unable to race as they watch the other players zoom below thus taking from them the one thing that they want, the victory of a three lap race. The hideous lapping of the Republican Primary goes on forever and ever and ever, probably, but it has much, in this instance, in common with the day glo excitement of Mario. Probably. My advice to candidates is to Beware the Blue Turtle Shell. My advice to players of Mario Kart is to vote.
