Looking at the state numbers, I see that there was a drop in abortions across the board it seems in 2005, and back up again in 2008. Wonder what happened in 05 to make it drop?
I think leadership has something to do with the waning and waxing of wickedness. Bush, for all his faults, was a morally-based born-again Christian who hated abortion as far as I know. Although I think Obama is a born-again Christian, I don't believe he has the same kind of moral compass.
The numbers are still horrific for any of the years, however, with only slight variations, really.
