The republicans have been keeping their powder dry. God help Obama if and when he actually becomes the nominee. 50MM Howitzers will unload.
People believe the election will center around the energy issue and perhaps, thanks to the situation in Georgia, national security.
It is my personal opinion though that abortion/infanticide will be the dark horse issue of this race.
I do not believe that a majority of Americans support abortion on demand, and I daresay that a significantly smaller percentage would be okay with infanticide.
