There were countless suits against Obama for years. They just sadly(related to Obama) went nowhere as this one will. Liberal judges don’t give a hang until a general election.
True, the courts always find they don’t have “standing” to sue. However the Democrats won’t bother with courts. If Cruz were nominated they would just have Democrat Secs. of State refuse to put him on the ballot in some swing states. That would force Cruz to sue to be put on.
