This ground has been covered numerous times, but it's fun to play. Congress voted an Authorization for Use of Military Force , authorizing the President to undertake military action against Iraq.
Paul understands that, and I'm sure would acknowledge the Constitutionality of that action.
If not, then the Authorization for Use of Military Force , authorizing the President to undertake military action against Afghanistan would be unconstitutional as well.
Paul voted for it, he never votes for anything unless authorized by the Constitution, so both Authorizations are fine.
But it’s not a “declaration of war” unless Congress says “we declare war on X country” - so say the moonbats.
I think you have to spin around three times and throw dog poop on their shoes, too, to make it official.
