Here's why the firestorm over Ted Cruz's Canadian birth is nothing like the Obama 'birther' controversy

Top-tier presidential candidate and Sen. Ted Cruz (R-Texas) has faced another round of questions over his White House eligibility over the past week, reviving a firestorm over the issue that first erupted two years ago.

Republican front-runner Donald Trump brought the subject to the forefront this week, after he insinuated in a Washington Post interview that Cruz's birth in Canada would be a "precarious" legal issue for Republicans if they nominated him.

"Republicans are going to have to ask themselves the question: 'Do we want a candidate who could be tied up in court for two years?' That'd be a big problem," Trump said, according to The Post. "It'd be a very precarious one for Republicans because he'd be running and the courts may take a long time to make a decision. You don't want to be running and have that kind of thing over your head."

Cruz first released his birth certificate to The Dallas Morning News in 2013. The day after, he said in a late-night statement that he would renounce his Canadian citizenship. Amid the latest firestorm, his campaign released his mother's birth certificate to the conservative website Breitbart on Friday.

Back in 2013, Trump said that Cruz was "perhaps not" eligible to run for president. Trump was once one of the most prominent people questioning the birthplace of President Barack Obama, who eventually released his long-form birth certificate in 2011.

But the questions about Cruz have little, if any, comparison to the conspiracy theories about Obama's birthplace. The "birtherism" that dogged Obama stemmed from the fact that his father was born in Kenya. But Obama's mother was born in Kansas and Obama himself was born in Honolulu, according to his birth certificate, though many conspiracy theorists are skeptical about the document.

Cruz's situation is quite different, in that he was actually born outside the US. He was born in Calgary, Alberta, to a father from Cuba and a mother from Wilmington, Delaware.

From the legal experts to who The Dallas Morning News and others have spoken in investigations over Cruz's eligibility, the US citizenship of Cruz's mother at the time should satisfy the constitutional requirement of being a "natural-born" citizen. The Constitution does not define what "natural born" means, but the expert consensus is that a person only has to be a US citizen at birth to meet that threshold.

Cruz once had dual citizenship. He said in 2013 that he would renounce his Canadian citizenship.

"Because my mother was a US citizen, born in Delaware, I was a US citizen by birth," he said in a 2013 statement. "When I was a kid, my Mom told me that I could choose to claim Canadian citizenship if I wanted. I got my US passport in high school. "
