Ted Cruz won big in Utah, but his almost equally big loss in Arizona — Donald Trump thumped him 47 percent to 25 percent — should be a warning sign to his campaign: you can’t out-Trump the Trump.

The headlines for Cruz the morning after his great Utah victory are astonishingly bad for him heading into Wisconsin — talk of patrolling Muslim neighborhoods, as if we live in a police state, and the name-calling exchange with Trump about their wives.

Cruz has one big shot at the increasingly dwindling likelihood that he can beat or pull close to Trump before the convention: he has to be the candidate of economic growth, opportunity and basic moral decency. The conservative candidate you can trust not to embarrass us.

Did the Cruz campaign learn nothing from the collapse of Marco Rubio?

Take a deep breath, Ted Cruz, get a good night’s sleep, and focus.
