Ted Cruz has opened a modest 4.8 point lead over Donald Trump in the winner-take-all state of Wisconsin, according to a new Washington Free Beacon poll. An Emerson poll shows Cruz with a slim 1-point lead. Forty-two delegates are at stake in the April 5 primary.

The liberal Salon is suggesting that the state is Cruz’s “last chance,” writing that “the conventional wisdom says Cruz has to win there in order to even sustain the argument that he might be worthy of taking the nomination on the second ballot at the convention if Trump comes up short.” The Washington Post is more balanced, though it does call Wisconsin “the Masada of the Stop Trump movement,” citing the millions of advertising dollars pouring into the state.

The Post reports that Trump’s coarse act might not play well in the Badger State. “There’s kind of a fundamental decency about Wisconsinites that you can’t downplay,” conservative talk show host Charlie Sykes told the newspaper. “We’ve never had a huge division between the tea party and the establishment. We’ve got think tanks and radio talk shows that have been through the fire and are really intellectually driven. And you don’t get that elsewhere.”

Whether or not it is do-or-die, Ted Cruz will be campaigning hard in Wisconsin. Said wife Heidi on Wednesday, “We’re going to be in this state from now through the election.”

Heidi Cruz herself has become an issue in the campaign after Donald Trump attacked her in revenge for an Anti-Trump SuperPAC add that used an old nude photo of his supermodel wife Melania from GQ magazine. (An ad, not incidentally, that had no connection to Cruz or his campaign.)

Cruz, in a fiery defense of his wife Thursday, ripped Trump as a “sniveling coward.”

“It’s not easy to tick me off,” Cruz told reporters in Wisconsin. “I don’t get angry often. But you mess with my wife, you mess with my kids, that’ll do it every time. Donald, you are a sniveling coward and leave Heidi the h*** alone.” Added Cruz, “It is not acceptable for a big loud New York bully to attack my wife.”

Cruz didn’t stop there. He suggested the billionaire is scared by “strong women” and “real men don’t try to bully women.”

Trump’s campaign manager Corey Lewandowski called Cruz’s comments an “effort to gain attention to try and stay relevant in a race that he has lost.” This is the same Corey Lewandowski currently under investigation in Florida for battery after manhandling and bruising female reporter Michelle Fields at a Trump event earlier this month.

Meanwhile, there is further evidence that Lewandowski’s assertion the race is “lost” is premature. The Wall Street Journal is reporting that Cruz is likely to end up with 10 more delegates in Louisiana than Trump despite the billionaire winning the vote. Both men earned 18 delegates from the March 5 primary. However, as reported by WSJ and The Hill, Cruz will likely pick up the five delegates earned by Marco Rubio, as well as the state’s five unbound delegates.

The publications also note that Cruz has “scooped up” five of Louisiana’s six positions on the Republican convention’s rule-writing committees. As The Hill put it, “If Trump doesn’t reach the delegate threshold to win the GOP nomination on the first ballot, Cruz-dominated committees could work to block Trump from winning enough delegates to claim the nomination on following ballots.”

On Friday morning, Cruz attempted to move past the spat over the wives to focus on Trump’s positions and to argue that the real estate mogul is poorly qualified to be president. He also reminded voters that Trump ducked the most recent scheduled GOP debate, the first debate since Rubio dropped out, winnowing the field to three. Cruz said Trump is “scared” of debating him because it would expose Trump’s poor grasp of policy. “Donald has a real problem,” Cruz said. “He doesn’t know what he’s talking about. He has utterly no idea.”
