The President is granted some rather broad leeway in 'Faithfully executing' the laws of this country... do note it doesn't say fully at the time approved of by Congress. The Cons in CONgress know this so past the political stunts they know it is a dead issue.
Just what part of the Libyan war did President Obama continue and what law did he not enforce.
I was around during the hate all things Clinton era with Newt leading the Congressional charge to hang 'em high. That is NOTHING like the animus against President Obama. I'd opine we would have already had the Impeachment if ANY of what you are claiming were truly violating the Office, duties of the Presidency or the Constitution.
Stirs the right wing base but fails past that.
