Exactly. We screamed for years about Obama and the Republican leadership did squat. Wouldn't and didn't want to touch it.
You can bet though that Democrats will have no qualms about going after Cruz on this every chance they get. They'll use the courts and the press will report on it ad nauseum.
There's no way that this can or will be resolved until it's in the courts. Cruz needs to get out in front of this, handle it and take it off the table.
There is no need to resolve it unless Cruz becomes president-elect, and then Congress has the power to decide whether or not he is constitutionally qualified. The 20th amendment anticipates an unqualified person becoming president-elect. The question is for Congress to take up, not the courts.
The candidates are free to risk an adverse ruling from Congress, and each voter will decide whether or not to vote for a candidate based on what that voter believes.
FWIW, the courts have taken up the question indirectly, in citizenship cases, and universally, without exception, express the principle that a person born abroad is not an NBC.
