Dual citizens are not qualified to serve as president as they may have divided loyalties.
Perhaps I should have asked for a clarification of your post before I replied.I assumed that you meant that they were *Constitutionally barred* from the Presidency and that was my mindset when I answered.I'd wager that *that's* not the case,although I'm no Constitutional scholar.Even if I'm correct the "divided loyalty" charge during a campaign would,I suspect,be a powerful...and effective...one.
