I've heard of Draft Newt and Americans for Rice, but Draft Wilberforce may have them all beat.
As their website says, Draft Wilberforce '08 is ...
... the movement to get eighteenth century British reformer William Wilberforce to lead America ... He has united people of all races, faiths and political beliefs with a new vision of leadership – marked by conviction, courage and the common good. Wilberforce leads with a spirit of civility and collaboration. From PETA to Focus on the Family, Americans are coming together to say “we need William Wilberforce today.”
Finally, a candidate who unites us!
