The GOP candidates are all stumbling over the Iraq question: “Knowing what we know now, what is a mistake to invade Iraq?”
But the real question is “Know what we knew then, what is a mistake to invade Iraq?” This was the fulcrum on which 2008 tipped to Obama over Clinton. (Obama had opposed the war at the time, while Clinton voted to authorize).
There was enough information at the time, to make the right decision. People with the requisite good judgement, wisdom and courage opposed it at the time, knowing what we knew then.
The hindsight qualifier of “what we know now” makes the question so easy as to be meaningless. Sure, it’s surprising that Republicans can’t give a simple straight answer. But even more curious: why are journalists serving up this pointless softball to the Republican field?
