If you had to sum up President Donald Trump’s second term so far in one word, you could do worse than “epic.”

Trump may be on the path to the most consequential presidency since Ronald Reagan’s. 

We don’t know how it will end — an unforeseen crisis could upend everything — but the emphasis has been on governing ambition from Day 1.

Even if Trump’s second term ended tomorrow, he would have left a significant mark. 

Consider his signature issues of trade and immigration. 

For all the talk about how he doesn’t have core convictions, Trump has favored tariffs for decades and has instituted a tariff regime that — absent discrediting economic turmoil — is likely to endure. 

This would have seemed almost unthinkable when Trump descended the elevator in 2015, and a relatively free-trade consensus prevailed in US policy. 

He’s brought border crossings to a historic low, and the United States could experience negative net migration for the first time in 50 years.

Again, this is a big change, and one that it’s hard to imagine anyone besides Donald Trump effecting. 

He’s dealt a blow to DEI programs in the federal government and is making it harder for colleges and universities to pursue race-conscious policies.

His election coincided with the beginning of a pullback from DEI in the private sector, one that his administration has encouraged. 

DEI was the culmination of a half-century campaign by the left for quotas in hiring and admissions and other racialized policies. Trump’s counteroffensive could represent an inflection point. 

He’s signed a tax and spending bill that makes permanent the tax cuts from his first term, funds a large-scale investment in immigration enforcement and includes a meaningful reform of Medicaid. 

He bombed the Iranian nuclear program, at the very least setting it back for years. 

He cajoled commitments for greater defense spending out of NATO countries. 

Almost any one of these items would be a notable first-six-months accomplishment, but he’s done them all, with lots of other activity besides.

His environmental and energy officials are rolling back the left’s climate agenda.

Trump defunded public broadcasting and kneecapped the Department of Education (for now).

His administration has taken important steps to protect female sports and to keep minors from being subjected to “gender-affirming care.”

He’s pushed universities into adopting reforms and probably upended forever the assumption that billions of federal dollars would flow to top universities as a matter of course. 

His election was both a symbol of, and a catalyst for, the woke tide’s receding. 

Trump has what is, in recent memory, an unprecedented grip on his party and has remade it in his image over the last decade.

If a Trump-endorsed GOP nominee wins the general election, he would be the George H.W. Bush to Trump’s Reagan. 

In sum, the rise of Trump in 2016 represented a break with what had been the post–Cold War consensus, although it was incompletely realized and seemingly a political fizzle when voters ousted him in the COVID election of 2020.

Biden was a partial return to a more conventional politics.

Now, with his second term, Trump is more fully effecting a transition to a new era — which alone makes him a highly consequential figure. 

The usual caveats apply: Again, a catastrophe could scramble all of this, and to say Trump is important is not to endorse everything he’s doing, whether big (e.g., the tariffs) or small (e.g., firing the Bureau of Labor Statistics commissioner).

Since he’s done so much unilaterally, it’s subject to relatively easy reversal if a Democrat is elected in 2028.

But there’s little doubt we are witnessing something historic. 

Steve Hayward called his volumes on the Republican giant of the 1980s “The Age of Reagan” — and Arthur Schlesinger wrote both “The Age of Jackson” and “The Age of Roosevelt.”

The equivalent of Hayward or Schlesinger decades from now will probably be justified in continuing the trope: All indications are that we are living in the Age of Trump.
