My sister has dual citzenship having been born in Ireland, and my brother and I obtained Irish passports a few years ago because our mother and grandmother were born there. None of us is running for President (sadly), but I would expect the Baggers to get all huffy about "where his loyalties lay". Doubt it will happen though. Some great tweets on this here.
WASHINGTON — Born in Canada to an American mother, Ted Cruz became an instant U.S. citizen. But under Canadian law, he also became a citizen of that country the moment he was born.
Unless the Texas Republican senator formally renounces that citizenship, he will remain a citizen of both countries, legal experts say.
That means he could assert the right to vote in Canada or even run for Parliament. On a lunch break from the U.S. Senate, he could head to the nearby embassy — the one flying a bright red maple leaf flag — pull out his Calgary, Alberta, birth certificate and obtain a passport.
“He’s a Canadian,” said Toronto lawyer Stephen Green, past chairman of the Canadian Bar Association’s Citizenship and Immigration Section.
