Such is the US president’s narcissism that he would see a Democratic victory as proof that he’s indispensable – meanwhile, his every decision spells calamity for voters

What is Donald Trump playing at? If it’s true that the best way of understanding the behaviour of an organisation is to assume it’s controlled by a secret cabal of its enemies, perhaps that same logic extends to the current conduct of the president of the United States. Maybe he secretly wants Republicans to lose the looming midterm elections that will decide the balance of power in the US for the next two years and for which the first postal ballots were sent out today.

That’s not as mad a theory as it sounds. Indeed, there are at least two reasons why Trump might either be unbothered by Republican defeat in November or even covertly desire it. We’ll come to those, but let’s start with a pattern of behaviour that is hard to explain as anything other than calculated self-sabotage.

Number of new jobs being added has been fluctuating, with private companies adding 38,000 jobs in August

The US economy added 162,000 jobs in August, an uptick after a sluggish summer for the labor market.

The unemployment rate held steady at 4.1%, still down from its most recent peak of 4.5% last November, according to new data from the Bureau of Labor Statistics (BLS). Despite the relative stability of the unemployment rate, the number of new jobs added to the economy has been fluctuating, going from 214,000 in March down to a 21,000 gain in July and then back up in August.
