Trump offered a bountiful batch of campaign promises that come due on Day 1

WASHINGTON — After Donald Trump becomes president again on Monday, he is on the hook for achieving a hefty chunk of his promises even before the day is out. One of those promises is to make you dizzy.

“Your head will spin when you see what’s going to happen,” he said of Day 1.

Steady yourself. This is some of what the Republican promised voters he would get done on his first day in office:

— Launch the largest deportation in U.S. history to remove all people in the country illegally.

— Close the border.

— End automatic citizenship for everyone born in the U.S., known as birthright citizenship.

— Sign pardons for some or many of those convicted or charged in the Jan. 6, 2021, assault on the U.S. Capitol.

— Impose a 25% tariff on everything imported from Mexico and Canada and add a 10% tariff to duties already imposed on goods from China.

— Even before Monday, end the Russia-Ukraine war.

— End what he calls the “electric vehicle mandate.”

— Declare a national energy emergency to spur the approval of more drilling, pipelines, refineries, power plants and reactors.

— Cut federal money to schools that push “critical race theory, transgender insanity and other inappropriate racial, sexual, or political content onto the shoulders of our children.” Also cut money to any schools that have a vaccine or mask mandate.

— Take steps to uproot the “deep state.”

All of that on Monday?

Not likely. Trump simply can’t accomplish all he said he will do on Day 1 because there are two more branches of government — Congress and the courts. The constitutional right to birthright citizenship, for example, cannot be ended with a stroke of his pen. (Moreover, in 2017 he considered Jan. 21 — his first full day on the job after the Jan. 20 inauguration — to be his Day 1.)

But as other presidents have done — and as Trump did aggressively and with decidedly mixed results in his first term — he will quickly test the limits of his executive power.

The power to pardon is within his grasp, and he can steer border enforcement efforts, tweak tariffs and find ways to spur energy production without Congress necessarily having to pass a law. Yet many of his executive orders will essentially be statements of intent — stage setters for struggles to come.

Here’s a closer look at what he promised to do on Day 1:

“On Day 1, I will launch the largest deportation program in American history.”

Under this core promise, Trump would unilaterally declare a national…
