Cruz could come out today and loudly and roundly condemn the ad, and that still would never be enough. And no... I don't think a PAC (that opposes Trump and has no ties to any campaign) should attack anyone's wife.
So enough with all the manufactured outrage.
There is no fake outrage - Trump simply said that if Cruz-supporting PACs are going to smear his wife then Heidi is fair game too. He warned of it to give a chance for Cruz to call off the dogs which Cruz can clearly do. Trump doesn’t have PACs providing cover for him so if they go after his wife he will fight back.
It’s not hard to understand.
