No, NBC sent a memo out to its affiliates warning them her appearance could trigger an equal time request.
They do that every time a candidate appears on one of their entertainment shows to give the affiliates the choice of carrying the show.
I believe that only once, however, has an opposing candidate actually claimed his equal time.
Cruz should do this. It would demonstrate how smart he is, and it would give him more and better exposure.
If he does it first, by the time the other candidates do the same, the audiences will be bored with the idea. Getting in first will take advantage of this opportunity.
