We have witnessed tonight a momentous election with far-reaching implications for the country -- in Mississippi, where the Associated Press is projecting that Democrat Travis Childers has won the special election for the open GOP House seat.

With 90% reporting, Childers leads 52%-48% -- and with the strongholds for GOP candidate Greg Davis mostly in, and some of Childers' stomping grounds still out. And all of this happened in a district that went 62%-37% for President Bush in 2004.
