"Winkler said Trump will need to prove that he is being "injured" by Cruz being in the race in order to show he has "standing" to sue."

I am thoroughly unqualified to say anything wrt Cruz being NBC or not. However, as a sane rational individual I can clearly state that every American citizen has standing at every point during his life to make a claim against someone he believes to be unqualified to be president, e.g. Obama.

I am injured by the continuous actions of a man who either is not NBC, or more likely is NBC but is guilty of a felony in claiming foreign status in order to get whatever fellowships he got to attend the various colleges he attended.

You can believe what you want, but courts decide who has standing, and when they decide against you, there is nothing you can do about it.

Same with "reasonable expectation of privacy." That is defined by a court (a matter of law), not by a jury of your peers.
