President Donald Trump is warning of an economic crash if he loses reelection, arguing that even voters who personally dislike him should base their ballots on the nation’s strong growth and low unemployment rate.

But privately, Trump is growing increasingly worried the economy won’t look so good come Election Day.

The financial markets signalled the possibility of a US recession this week, sending a jolt of anxiety to investors, companies and consumers.

That’s on top of concerns over Trump’s plans to impose punishing tariffs on goods from China and word from the United Kingdom and Germany that their economies are shrinking.

Though a pre-election recession here is far from certain, a downturn would be a devastating blow to the president, who has made a strong economy his central argument for a second term.

Trump advisers fear a weakened economy would hurt him with moderate Republican and independent voters who have been willing to give him a pass on some his incendiary policies and rhetoric.

And White House economic advisers see few options for reversing course should the economy start to slip.

Trump has taken to blaming others for the recession fears, mostly the Federal Reserve, which he is pushing for further interest rate cuts.

Yet much of the uncertainty in the markets stems from his own escalation of a trade war with China, as well as weakened economies in key countries around the world.

Some of Trump’s closest advisers have urged him to lower the temperature of the trade dispute, fearing that further tariffs would only hurt American consumers and rattle the markets further.

The president blinked once this week, delaying a set of tariffs in an effort to save Christmas sales.

Aides acknowledge it is unclear what steps the White House could take to stop a downturn. Trump’s 2017 tax cut proved so politically unpopular that many Republicans ran away from it during last year’s midterms.
