I believe Trump settled it when he said he would consider Cruz for VP (After he made a big stink about his citizenship). So I guess the challenge in Illinois sufficed for Trump so he is able to consider Cruz again. Or do you disagree with Trump?
When was that? The last I heard was he said he couldn’t pick Cruz unless it was settled first. As far as I know he still maintains it isn’t settled, which is true. The fact that you have bonafide experts arguing both sides clearly shows it’s not settled. I believe if Cruz were the nominee Democrat Secretaries of State in at least some swing states would refuse to put him on the ballot. Then Cruz would have to sue, and there is no way of knowing how it would be decided.
BTW, Trump saying he would consider something is his default answer. I could say I might consider moving to Iran. For about 2 seconds. So what? He could consider it and decide he can’t pick Cruz because of the birth issue.
