Well, the voters have spoken.
My take is that a lot of people were fed up with GOP incompetence and graft. Tends to be a characteristic of whichever party is in power for too long. This is a wake up call for the GOP, get back to the basics of conservatism, fiscal responsibility, and rooting out corruption within your ranks.
The Dems have won so leave sour gripes elsewhere. This is certainly not the end of the world.
On a positive note, having Pelosi as speaker virtually guarantees a GOP victory in 08'
