The Trump factor is shaping global politics, one election at a time — just not necessarily to the president’s taste.

In major votes in Canada and Australia over the past two weeks, centrists saw their fortunes revived, while parties that had borrowed from the MAGA playbook lost out.

President Trump has been back in power for only three months, but already his policies, including imposing tariffs and upending alliances, have rippled into domestic political battles around the world.

While it is too soon to say that anti-Trump forces are on the rise globally, it is clear that voters have Mr. Trump somewhere on their mind as they make decisions.

Political cousins

Canada and Australia share a lot in common: a political system, a major mining industry, a sovereign in King Charles. Now they also share a remarkable political story.

In both countries, before Mr. Trump was inaugurated, the center-left ruling parties had been in poor shape and appeared poised to lose power. The front-runners in polls were the conservative parties, whose leaders flirted with Trumpian politics both in style and in substance.
