No, they did not decide on the merits.
Cruzbots lie and that lying is going to get them in the end.
Actually, the PA case WAS decided on the merits:
"A Pennsylvania judge affirmed Sen. Ted Cruzs status as a natural born citizen Thursday and dismissed a lawsuit that sought to remove the candidate from the states Republican primary ballot, the Pittsburgh Post-Gazette reported."
The rest were tossed before they ever got to the point of arguing the merits.
I think the IL Election Board also got past the question of standing, but it's opinion was even worse than Pellegrini's.
The Pennsylvania Supreme Court issued a three line affirmation of Pellegrini's opinion - zero remarks on the rule of law.
The Illinois case died when the objector failed to serve Cruz personally, with notice of the suit.
