Newt can always debate himself...he’s taken more than one position on many issues (only later to reverse course calling his previous position a “mistake”).
Kind of like when Rick said in the debate that voting for Medicare Part D was a mistake?
Let's not even get into Romney's flip-flops on abortion, gun control, embryonic stem cell research, cap-and-trade, etc. Even worse are all the liberal positions he refuses to flip-flop on like Romneycare and his Obama-cloned economic redistribution policies of welfare for the poor and higher taxes for the rich.
