Donald Trump’s response to this dilemma is protectionism, immigration restriction, and a big helping of his own often-claimed superhuman toughness and competence. It’s maybe not a very adequate answer, but it’s an answer. What’s Marco Rubio’s answer? What’s Jeb Bush’s? What’s Chris Christie’s?

Listen to Marco Rubio describe his priorities for his first day in office. They include repealing Environmental Protection Agency rules, repealing the Common Core, and canceling the Iran deal.

Ted Cruz’s first priorities are ordering the Justice Department to investigate Planned Parenthood, ordering the IRS to stop persecuting religious liberty, canceling the Iran deal, and moving the U.S. embassy in Israel to Jerusalem.

Jeb Bush’s first priorities include repealing Obamacare, lifting regulatory burdens on businesses, and eliminating gun restrictions. He’ll also end the president’s orders authorizing illegal aliens to remain in the country, insisting that this aim can only be achieved by legislation. Only the last of this series bears very closely on the anxieties discerned in the Post poll—and even that last is only provisional. It remains Jeb Bush’s intention to do by legislation what he objects to President Obama doing by executive order.
