DONALD TRUMP has flown off to Florida in his last trip on Airforce One. Does he contemplate spending his declining years playing golf or is he most worried about the declining value of his overleveraged assets? Or perhaps the predatory intentions of the New York District Attorney?

No-one outside of Trump’s persistently large base of supporters in the US will feel much sympathy if the the ex-president walks the perp walk in a jump suit to match his complexion, but there is a measure of anxiety in the US elite about his future plans.

Whether the US political Establishment thinks that greater political advantage is served by a war of vengeance against him or, alternatively, that the system can be tweaked to accommodate the forces catalysed by his eccentric presidency hangs in the balance.
