My point is a person should not be allowed to vote in two places. I'd add that anyone in elected office should not be a dual citizen.
As it stands now, we have people from a lot of nationalities in important US positions who aren't really representing us. Nikki Haley comes to mind.
I agree completely about voting. Most states you must be a resident for a period of time to vote. Might be a short period of time, but a resident. Same rule should apply. I've no concerns about Nikki Haley. She's a citizen, born here, just like Hillary and others. Disagreeing with her politically is a different matter.
You're missing the point concentrating on dual citizenship, which isn't a real issue in the context of Omar's accusations. The issue is loyalty. Naturalized citizens swear to support the Constitution and renounce allegiance and fidelity to any foreign entity, including those which might be of their origin. Do they, all of them, I don't know. But it's an issue that's been litigated often. And which, of course, doesn't apply to illegals. But the loyalty issue is far more significant than the canard of dual citizenship, though much more difficult to address short of individuals who, as US citizens, serve our enemies.
I don't know how much people think about that. Rahm Emanuel did. Though born here, he had Israeli citizenship through his parents, and knew to renounce it before being subject to military service. I doubt Cruz thought about it. Obama I agree the birther issue was a distraction, though my understanding is he might have been a Brit, an Indonesion, both or neither. But he didn't bother to renounce anything, just in case. But as I noted, it would have been his parentage rather than his actions. And there were so many more important issues to discuss which didn't play into his hands. Consider the example of Cuba I alluded to, though there are others. Would you deny the right to serve in Congress to a Cuban immigrant because the Castros wouldn't allow renunciation.
