First Donald Trump said Ted Cruz should seek a “declaratory judgment” concerning his eligibility to be President. Now Trump said he has “standing” to challenge

Mr. Trump also did not relent on Mr. Cruz’s eligibility to be president. In an interview on the sidelines of the South Carolina Tea Party Coalition convention, Mr. Trump maintained that Mr. Cruz’s being born in Canada was a problem, and he noted that lawsuits questioning Mr. Cruz’s status as a “natural born citizen” are already being filed. Despite saying during last week’s debate that he would not file his own lawsuit, on Saturday Mr. Trump would not rule out the possibility.

“I’ll think about it,” Mr. Trump said. “It’s not something that I would want to do. It’s certainly something I would have standing to do. It’s not a priority. Because I’m beating him by so much, anyway, what do I have to bring a suit for?”

Someone on Trump’s staff is giving him awful federal courts advice. A declaratory judgment would not work, and he does not have standing. This is a yuge mistake.
