Mitch McConnell tells President Obama to seek approval from Congress on action against ISIS. I've never been of the opinion that that is necessary in a case like this. But it's certainly always a wise and prudent step. And McConnell makes the point that it shouldn't be a problem since there appears to be broad support both in Congress and in the country at large to pursue action at least largely limited to air support of the ground forces of Iraq and other countries. So far, so good. So what's the problem?
