I do not know the answer, I could speculate. My guess is he has internal polls showing his message is getting out. Why waste time and money if the people are paying attention... Some would accuse him of being vindictive if he were to sue Cruz now.. Seems more prudent to not totally turn off Cruz supporters.. He needs them to win the general.
Trump has not been who I was expecting. But that does not translate to, he is who I want.. I have no clue who will be on my state’s primary ballot..
I still have to stand by my original statement. The question does need put to rest one way or the other. We've got people tearing each other apart here over it. Trump is one of the few people who might have standing to bring suit and get the case heard. He knows this and apparently believes he'd be doing us a favor if he went ahead and did it, judged by his on words on the subject. So why, if he really is doing this for the benefit of all of us doesn't he go ahead and do what he professes to believe would be a great favor to us?
