There is no, none, nada, zippo evidence establishing that Cruz had a damn thing to do with putting the picture of Trumps wife on an ad. Why do you guys persist in that lie?
Lying is what they do. It's pathological.
In other words, the ad says: "Because Donald Trump's wife posed nude, she is a brazen slut. And because Ted Cruz's wife did not pose nude, she is not a brazen slut. Therefore, you should vote for the man whose wife is not a brazen slut."
But whether or not Ted Cruz approved of it, the reality is that it is out there, and it has his name on it. So in politics, one's friends can often do more damage than one's enemies. In this case, Cruz's friends painted him out to be a hypocritical holy-joe. And the ad, with HIS name on it, made his wife fair game, whether he wants it or not. His friends brought her into it through their attack on Melania Trump.
Not saying that Cruz did it. But he'd be smart to shut his friends up, because he's a rank amateur when it comes to anything other than just talk.
