The presumptive president and the presumptive prime minister, both intoxicated by the prospect of power, clearly have much in common.
Apart from their shock of blond hair, they’ve both crafted a bluster and an ability to maximise the media to exploit the fears and prejudices of voters.
Crucially, their biggest common denominator is their inability to grasp the truth but to be believed.
Somehow you feel that they would actually rub along very well together but, there again, could there really be a “special relationship” and trust between two men who use a formula of distortion and deception to get their way?
Like Boris, the de facto leader of the campaign for Britain to leave Europe, The Donald is also a Brexiteer.
As Trump told that other trickster, Piers Morgan, over the weekend: “ A lot of the migration and a lot of the acceptance of people is because of the EU and I think that’s been a disaster.
“I’ve dealt with the European Union and it’s very bureaucratic. Personally, in terms of Britain, I would say what do you need it for?”
It was another masterclass of simplistic thinking which Trump has become renowned for in his campaign to win the Republican nomination and then to enter The White House in November.
Sure, there’s a long way to go but the movement to stop Trump appears to get weaker while he seems to get stronger as every day goes by.
It’s Trump who is constantly sought out by the interviewers and the cameras despite everything he’s said about Muslims, Mexicans and misogyny while his most likely opponent, Hillary Clinton, is finding it difficult to shake off her democratic rival Bernie Saunders.
Boris Johnson appears to have no such problems as he cavorts around the country in a big bus emblazoned with the lie that the £350 million we give to the EU every week could pay for the NHS.
It’s a claim which Trump would be proud of because what the paint job doesn’t say is that we get back a rebate (thanks to Mrs Thatcher) and other paybacks which reduce this amount to less than half.
But that hardly matters when there’s the prospect of the leadership of the Conservative party to be won should David Cameron slip up, lose the referendum, and be deposed come the party conference in October.
Like The Donald, Boris has a history of being loose with the facts since he was fired as a reporter on The Times for making up quotes and then dismissed by the former Tory leader Michael Howard when he didn’t come clean about an extramarital affair.
Yesterday, after Boris was criticised for comparing the ambition of Adolf Hitler to the aims of the EU, those unlikely bedfellows of Chancellor George Osborne and Labour’s Ed Balls were joined by the former Lib Dem business secretary Vince Cable to declare that leaving Europe was a one way ticket to a poorer Britain.
But this didn’t scare Boris who, wielding a hot iron during a visit to an anti EU clothing factory, said he would flatten his opponents.
With just 38 days left until the referendum, we can expect the argument to become angrier and more bitter while the claims from both sides are likely to get even wilder.
Alas, this is the world we live in, where agreement on facts has never been in shorter supply and where politicians can twist and trick their way to win over the masses.
It’s a terrifying thought that Donald Trump and Boris Johnson could effectively be the leaders the western world by the end of this year.
