So this was an IMPORTANT biographical fact that has never been reported by the MSM. Having once had dual citizenship doesn't disqualify Obama from running but it is a very interesting biographical fact that has been suppressed. I never heard of another presidential candidate that ever had dual citizenship. If John McCain had once held dual citizenship, you think this fact wouldn't be all over the MSM?
I wouldn't say suppressed. I'd say ignored, because it is completely irrelevant. The whole Kenyan citizenship was a bureacratic matter that was resolved when he turned 18. Obama did nothing to acquire dual citizenship and he did nothing to retain it. If he had, then you'd have a story.
I understand that in the recent past if you had gone to DU and other similar sites you would have seen a whole series of posts, much like this one of yours, questioning McCain's qualification for the presidency since he was born in Panama. Some may well have made the same claims about dual citizenship in Panama. None of that got any play in the MSM, I imagine because it too was irrelevant.
