Probably one of my favorite lines is Romney's, "Attacking me is not an agenda.". That's the best line of the night.
If you're a President named Obama ("Bam" to the headline writers at the NY Post) and you forget your high-minded rhetoric from four years earlier, going all-negative all the time, and getting personal and snippy when your failed record comes back to haunt you, you might suffer from . . ."Bam-nesia."
It's "bayonets and horses." Or "the eighties called..." Or one of those.
