Victor Davis Hanson explores for National Review Online whether President Trump can remodel the Republican Party.

The Republican-party establishment is caught in an existential paradox.

Without Donald Trump’s populist and nationalist 2016 campaign, the GOP probably would not have won the presidency. Nor would Republicans now enjoy such lopsided control of state legislatures and governorships, as well as majorities in the House and Senate, and likely control of the Supreme Court for a generation.

So are conservatives angry at the apostate Trump or indebted to him for helping them politically when they were not able to help themselves?

For a similar sense of the paradox, imagine if a novice outsider such as billionaire entrepreneur Mark Cuban had captured the Democratic nomination and then won the presidency — but did not run on either Bernie Sanders’s progressive redistributionism, Barack Obama’s identity politics, or Hillary Clinton’s high taxes and increased regulation. Would liberals be happy, conflicted, or seething? …

… Republicans concentrate on what they like in the Trump agenda — military spending increases, energy expansion, deterrence abroad, tax and regulatory reform, and the repeal and replacement of the Affordable Care Act — and they ignore the inherent contradictions between Trumpism and their own political creed.

But there are many fault lines that will loom large in the next few years.
