But heading into the November midterms, where Democrats face losing control of Congress and even his own re-election in 2024, Biden has changed his tune.

Why? Because however much he may have disappointed some Americans – on the chaotic withdrawal from Afghanistan, for example, or the highest inflation in four decades, or anything else – he wants them to remember that Trump is in the wings.

“Don’t compare me to the Almighty, compare me to the alternative,” Biden said last month on a trip to Washington state.

On Wednesday White House Press Secretary Jen Psaki told reporters they would “hear him with that mantra much more out there over the next coming months”.

Biden doubled down on Wednesday, lashing out at Trump’s Make America Great Again, or MAGA, movement.

“This MAGA crowd is really the most extreme political organisation that’s existed in American history, in recent American history,” Biden said.

Biden presides over a strong economy and has restored Washington’s global leadership in responding to the Russian invasion of Ukraine.

However, sky-high inflation hits every voter, while issues such as illegal immigration and Covid-19 vaccines are inflaming the right.

And if Republicans win the House or Senate, or both, as polls show is entirely possible, he will face two years of grinding obstruction and made-for-television investigations by a Republican Party still largely loyal to Trump.

So the bombshell leak this week of a Supreme Court ruling on the apparently imminent end to national abortion rights may ironically have done Biden a political favour.

Not only are Democrats expected to get fired up in defence of abortion rights, but Biden hopes he can tie the coming restrictions into a broader picture of an extreme right running wild. “What are the next things that are going to be attacked?” he asked on Wednesday.

Whether Biden’s attempt to define the election on such stark terms will work is open to question.

For many Americans, what he calls “extreme” – including the looming rollback of abortion rights – is exactly what they elected Trump to bring about back in 2016.

The right-wing publication The Federalist compared Biden’s “extreme” remarks to Hillary Clinton’s ill-fated statement during her campaign against Trump that his supporters were “deplorables”.

“A desperate Joe Biden is following her failed playbook,” The Federalist said.

For now, there is a preliminary war ahead of the midterms and even what could end up as a 2024 Biden-Trump rematch.

In Ohio’s closely watched primary contests to see who will represent the Democrats and Republicans in November, both leaders found signs that their brands are in good health.

Trump flexed his muscles by endorsing the ultimate winner of the Republican primary for the US Senate, J.D. Vance. An author and venture capitalist, Vance once called Trump “America’s Hitler”, but turned to embrace the former president and was rewarded.

Biden’s moderate brand prevailed in the Democrat’s primary win, with Tim Ryan, a politician who like Biden stresses his working class background and middle-of-the-road ideology, getting the nod to run against Vance in November.

Another relative moderate, Shontel Brown, won in a tough primary for a House seat race, after she was endorsed by Biden.

Struck by Trump’s “hold” on Republicans, Biden will “call out … where he feels are extreme policies and extreme comments and extreme positions”, Psaki said.
