Maybe what POTUS means by "Comey is McCabe" is that everything he is saying about Comey is actually re: McCabe. That would lead credence to the idea that Comey is not the bad guy (as Gowdy has inferred with his "history will be much kinder to Comey" statement). This would mean the Comey ordeal is smoke and mirrors just like the Stormy ordeal is a story well as the Syria situation is.
Comey battle= FBI/DOJ corruption battle.
Stormy scandal= getting through attorney client privilege and loosening up the public's view to accepting sexual scandals.
Syria conflict= "Iran is next" Q crumb
