Now whether or not someone can participate in debates is based upon an arbitrary polling figure. You have to be polling nationally at 15 percent. If that criteria had been applied in Minnesota, I would not have become the governor. Because at the time of the primary, I was only polling at 10 percent. But I was allowed to debate, and I proved that you could be at 10 percent and still end up winning. And I did it in a mere eight weeks.
