The name of Sen. Ted Cruz's U.S.-born mother reportedly appeared on a Canadian government document listing her as a citizen eligible to vote in the 1974 federal election there.it received the Canadian document in 2013 but didn't publish it because the GOP presidential contender – who now faces eligibility questions of his own from rivalsand Kentucky Sen.– wasn't yet a candidate.posted a story Friday as well, along with a lengthy response from the Cruz campaign asserting there was no question of Eleanor Cruz's American citizenship.According to Jason Johnson, Cruz's chief campaign strategist, the Republican presidential candidate's mom "was never a citizen of Canada," and couldn't have been one when her son was born because of residency requirements, Breitbart reports.Eleanor Cruz was born in Delaware, while her ex-husband, Rafael Cruz, was born in Cuba, obtained Canadian citizenship while living in Calgary and became a naturalized U.S. citizen in the mid-2000s, Johnson explained.TPM reports the document in question is a voter list of individuals who lived in the southern district of the city of Calgary, were over the age of 18 and were Canadian citizens, thus eligible to vote."The document itself does not purport to be a list of 'registered Canadian voters'," the campaign statement said. "All this might conceivably establish is that this list of individuals (maybe) lived at the given addresses. It says nothing about who was a citizen eligible to vote."TPM notes there's no other evidence Eleanor Cruz ever became a Canadian citizen, and that she and her son have consistently denied she was one.And, TPM reports, even if it were proven that Eleanor Cruz had become a Canadian citizen, she might well have remained a U.S. citizen too, maintaining a dual citizenship.Ted Cruz, who was a dual citizen, formally renounced his Canadian citizenship in 2014.
