Gingrich is asking for forgiveness, so its looking rather certain that he will run in 08. While it is true that at times history is made, 08 seems like one of those times it will just be replayed.
In 08 we will have a Gingrich / Rice ticket on the Republican side, and a Clinton / Obama ticken for the Dems. The Greens will most likely go with former Black Panther Elaine Brown. A good possibility would be a Elaine Brown / Matt Gonzalez ticket.
