And Morrison does not have to say “fake news” to echo the President at times. He complained about the media on Wednesday for running “completely false” and “completely misleading” accounts of his climate policies.
So when Morrison needs answers on how to win the next election, he will no doubt consider Trump’s formula – and whether it works in November 2020.
But political tactics do not transfer so easily across the Pacific. Those around Morrison are not planning a Trumpification of the Prime Minister for the simple reason that the intensely partisan tactics that work in the United States cannot work in a world where elections are won and lost in the centre.
Compulsory voting stays the hand of anyone who wants to appeal to the edge and forget the middle.
Trump is divisive in Australia and his friendship with Morrison may alienate some Australian voters, which means copying the President is no guarantee of victory.
Some of Morrison’s critics on the left see a world they fear, or perhaps secretly the almighty battle they want, when they make the Prime Minister out to be like Trump.
Imagine Morrison if that were so. He would not only skip the United Nations climate summit. He would ridicule it as a waste of time.
The fact that Morrison used his speech to the UN to talk about action on climate shows he does not want to lose voters in the middle who expect their political leaders to take it seriously.
And there is a gulf between the two leaders on the right of a superpower to dictate terms in the world.
“The future does not belong to globalists. The future belongs to patriots,” Trump said at the United Nations on Tuesday.
The fact that Morrison used his speech to the UN to talk about action on climate shows he does not want to lose voters in the middle.
What that means may require long study, but it is an immediate contrast with the Australian support for negotiated settlements between countries rather than the will of one group of patriots imposed on others.
“We will be more secure and prosperous in a global order based on agreed rules, not one based on the exercise of power alone,” Morrison told Asialink in Sydney in June.
