Name someone, not in your imagination of a lefty, who has called for impeachment for any of those reasons. The only one you are even close on is Iraq and the offense there is lying to congress about the reasons to invade, not the invasion itself. If anyone ever called for impeachment over the invasion of Afghanistan, I have yet to see it. As for the others? Hogwash.
I have a feeling this is a "leftys swirl clockwise" stance.
