Krauthammer vs Romney, Ctd

Rather than walking back his simply absurd statement that there is not a shred of evidence that Romney had anything to do with Bain from 1999 to 2002  – "any decision, any investment, any phone call, any meeting of any kind" (Romney denied this under oath, for Pete's sake) – Krauthammer doubles down on the lie:

Obama starts with the attack on the [Romney] outsourcing. It’s shown to be false. If there was any, it happened after Romney left Bain. So then the Obama people return with a second falsehood that Romney was running Bain until 2002. All the evidence is he was not.

Again, what's striking here is the lack of any relationship to reality. "All the evidence?" Is it simply impossible for neocons to admit they have made a mistake? Or do they have to keep on lying for ever?
