The cult of personality that has risen around Donald Trump has reached even more absurd levels in the new year. The latest development is that some conservatives are giving credence to questions about whether Sen. Ted Cruz, R-Texas, is a natural-born U.S. citizen.

As far as actual substance is concerned here, there is no real issue. Cruz is unquestionably eligible to be president. This is something that solicitors general for Presidents Bush and Obama explained in the Harvard Law Review last year. And for those who would dismiss such sources as too “Establishment,” the case for Cruz’s eligibility has also been outlined on several occasions by conservative constitutional lawyer and talk radio host Mark Levin, among many others.
