Who says Donald Trump lacks subtlety? The way he's raising "birther" questions about his chief rival for the nomination is worthy of Machiavelli.
"I'd hate to see something like that get in his way," Trump said of the fact that Sen. Ted Cruz, R-Texas, was born in Canada. Trump referred to the fact that the Constitution says "No Person except a natural born Citizen" -- whatever that means -- is eligible to be president.
"But a lot of people are talking about it," Trump continued, in an interview with Washington Post reporters, "and I know that even some states are looking at it very strongly, the fact that he was born in Canada and he has had a double passport."
Cruz flatly denied ever having a Canadian passport, telling CNN this is just one of those "silly sideshows" the media love to engage in. But there is no question that he was born in Calgary, Alberta, to an American mother and a Cuban father. And there is no question that he had Canadian citizenship -- before renouncing it in preparation for his presidential run.
