WASHINGTON -- Last week witnessed one of the most piqued foreign policy showdowns between the executive and legislative branch during the Obama presidency. And in a clash between a president allied with his secretary of state and vice president -- themselves former chairmen of the Senate Foreign Relations Committee -- it was a self-admitted newbie to international affairs who scored the win. The 19-0 Foreign Relations Committee vote to ensure congressional oversight of a final nuclear deal with Iran was unexpected, considering the current political climate in which bipartisan cooperation is increasingly scarce.
