If Cruz should win in Iowa, Trump will have suffered “injury-in-fact” (direct not indirect injury) which is a requirement of standing, if, repeat IF Cruz is ineligible.
McCain, Palin, Romney and/or Ryan could have been granted standing to sue Obama as the only other people to receive Electoral votes and have a legitimate chance to be elected if Obama was to be found to be ineligible. That again would be injury-in-fact. But none of them filed suit or were the lead plaintiffs in a class action suit.
Injury has to be concrete though, and it cannot be conjectural. How would Trump prove that a significant amount of Cruz support would flow to Trump when there are 10 other candidates in the race?
Trump would have to show a 3rd party not in the suit would not have affected the outcome. He would have to get other candidates to join his suit and they would collectively have standing.
I dont see speculation and hypotheticals winning any standing in any court.

The “injury-in-fact†will have been perpetrated by the voters, not Cruz. Maybe Clyde Barnum Trump will sue the voters.
