A resolution by the U.S. Senate, drafted after being given testimony from legal scholars and approved by members of Congress from both sides of the political aisle, could help sway a judge's decision. It could even help sway a judge's decision not take a case challenging McCain's eligibility.

And, again, that was part of its intended purpose.
