As I wrote recently, many Republicans have found the traditional Left ↔ Right spectrum increasingly unhelpful in identifying the GOP’s ideological tensions during the Trump era. If activists do, in fact, begin to define “conservative” as “pro-Trump” and “moderate” as “Trump-averse,” it seems all the more likely that the old taxonomy will give way to a new, more useful vocabulary.

But the paper’s findings could have political implications that extend far beyond diction, Noel told me. This could be an early signal that Trump-style nationalism is supplanting old-school conservatism as the Republican Party’s dominant ideology.

“If Trump is shaping and changing the next generation of Republican foot soldiers to think of conservatism as what he thinks it is … instead of what Paul Ryan thinks it is, he’s going to lead the party in that direction,” Noel said.

Exhibiting all the usual modesty of careful academics, Noel cautioned that it’s too early to drawn any definitive conclusions from their findings. He also noted that it typically takes a generation or so for a party to undergo a wide-scale ideological transformation like the one he was speculating about. And unlike modern conservatism—which William F. Buckley and his comrades spent decades articulating and popularizing before Ronald Reagan ever carried it into the White House—Trump’s brand of politics doesn’t yet have a robust support system or intellectual infrastructure in Washington.

That said, Trumpism has an unusual head start compared to the historical rises of other ideologies—it’s already being championed by the most powerful man in the world. And as long as grassroots Republicans are demanding fealty to Trump from their elected leaders—lest they be branded “moderates” and made vulnerable to primary challenges—Trumpism has a good chance to flourish and spread throughout the GOP.

Conservative purists, and perhaps many in the broader political intelligentsia, will no doubt object to conservatism being summarily redefined simply because voters and activists moved the goalposts. But Noel, who specializes in the study of ideology, takes a practical view of the philosophical debates on the right.

“People argue about these things forever,” he told me. “There are deep debates among conservative thinkers, and whoever ends up convincing more people wins. You can say, ‘That’s not real conservatism,’ but … at the end of the day, you’re wrong if no one agrees with you.”
