Donald Trump vs Ted Cruz: Trump Tell Cruz That Wives And Kids Should Be Off Limits

It looks like the marital circumstances of the Republican contestants are splashing into the main election scene. While Donald Trump on Monday agreed that the presidential candidates should not attack rivals' wives or kids, he added that his opponent Ted Cruz needed to "commit to that standard."

Trump gave the reply when Wisconsin radio host Vicki McKenna asked whether kids and wives should be off limits. He said: "Well, that's okay, but all you have to do is tell that to Cruz. Because he started it."

Strangely, it did begin last week when in an anti-Trump ad, an image of Trump's wife Melania, is shown nude in a photo for GQ magazine. The ad says: "Meet Melania Trump. Your next first lady." Even though the ad was run by an anti-Trump super PAC not connected at all with Cruz, Trump did not let up the accusation.

Trump told McKenna that it was "really naive" to think Cruz wasn't behind the ad. Reminded that a super PAC ran the ad, Trump responded, "a Super PAC that he is friendly with."

He denied that he pumped in a story into National Enquirer on Friday, claiming to disclose tasteless details about Cruz's life. "I don't know who did it, but it wasn't me," he said.

Cruz, on the other hand, clarified in Wisconsin Monday that the National Enquirer story was "complete garbage" and Trump was to be blamed.

"It is total lies, it was planted by Donald Trump's henchmen, and I don't think the people of Wisconsin or the people of America have any interest in tabloid trash," he said.

Cruz threw a challenge of a one-on-one debate as an alternative to a couple of televised town halls for this week.

"In all likelihood, Donald is going to turn me down," he said. "Why? Because he's scared of actually answering questions about substance. Because while he's very good at attacking and yelling and insulting, he does not have meaningful solutions to the problems facing this country."

The contest is expected to heat up next week if Trump does not win the Wisconsin primary on April 5. Cruz is said to be making inroads there.

Last week's Emerson College poll showed Cruz leading Trump by just one point, working out to 36 percent against 35 percent in the Wisconsin primary.
