It’s not Cruz’s PAC, it’s an Anti-Trump PAC. Cruz has condemned the ad, not that the news bothers to report that, but there’s no reason to assume he has any control over the PAC because the PAC is more anti-Trump than pro-Cruz (and a small fry compared to the Anti-Trump “Our Principles” PAC).
Trump did not “handle” the pro-Trump PAC that shut down; he made it clear where he stood and, as Trump fans, they honored that. The Washington Post was also trying to cause legal trouble over Trump’s PAC. Not the same situation here.
About all a super PAC does is run ads for or against candidates; Trump already has all the publicity he needs, so he doesn’t really need any super PACs. The media is not giving any of his competitors anything like so much free publicity.
Oh, Cruz has done none of those things. My bad.
BTW, I have a bridge in a swamp for sale. Are you interested?
Did you watch Lou Dobbs tonight? It would have opened your eyes.
