But as an obese man - which he veritably is, rather than just slightly over the insurance-company ordained BMI chart average, like so many of us - should the United States, nay the world, worry about this man's risk of heart disease, stroke or diabetes were he to assume power?
That's one question, but perhaps it's supplementary to the main one: would enough people be prepared to vote for an extraordinarily fat man to become President?
Not if the recent past is any guide. Chester A. Arthur (21st President), Grover Cleveland (22nd and 24th) and William Howard Taft (27th) were on the portly side, but more modern Presidents have been mere shadows of those hefty predecessors.
All sorts of maladies could be hidden from public view until recent times (ie, a President with Addison's disease - John F. Kennedy). Even now, in these days of full disclosure, the US has twice voted for a smoker as President (and a socialist of Kenyan descent to boot) but still, obesity remains the last threshold to cross. And not just in terms of presidential elections but also in the everyday; in our workplaces and the schoolyards.
It is perhaps, as many believe, the last type of "permissible" discrimination left, pointing up a basic truth about human nature: we are conditioned to find certain things repellent, we the sheeple, and our visceral fear and loathing of fat is hard to dislodge, no matter what percentage of the population cross the line into obesity.
Women have it much worse. In New Zealand we've had our obese Prime Ministers and business leaders, and even Kim Dotcom is seen as a bit of a cuddly counter-culture figure rather than whaled on for his girth. But we could never have an obese woman as Prime Minister; even our largeish female MPs are subject to constant and needless references to their bodies (Paula Bennett's weight, for example, clearly an ever-present consideration on the mind of John "Front Bums" Tamihere).
It's a sad fact of life that the plump woman is the most vilified of all. But most women can empathise with the struggle against fat, and that might be why Chris Christie, he of the defiant doughnut, is currently enjoying his highest poll ratings ever. When politics and power is a popularity contest, fear of fat might just be pipped by the power of the sympathetic female voter.
