Actually, there are some complications with his citizenship. You should look it up. The Canadians are not convinced he is certain to have US citizenship, and he has apparently dropped his effort to TERMINATE his Canadian citizenship, because he would have to prove, in a Canadian court, that he actually is a U.S. citizen, before the Canadians will terminate his Canadian citizenship. Under Canadian law, they can't let people become stateless. Proving his actual US Citizenship will be more difficult than you Conservatives are willing to admit… it's a #$%$ to find that your arguments did not work on Obama, but probably will work on Cruz.
