I’ve commented on ‘roundism’ before – our tendency to assign special importance to round numbers. Why is a 40th birthday such a big deal? Why do we delight in seeing a car’s odometer click over to 100,000? Why do we bring out the brass bands and bunting for centenaries?

Well, the first 100 days of a political leader’s being in power holds the same magic for us. Donald Trump has just attained this milestone, which he himself declared would mark a period of tremendous achievement.

It’s certainly been a period of tremendous excitement – a roller-coaster ride for the President’s friends and foes alike, and especially for people like President Putin who started as a friend and has now been re-categorised.

I don’t intend to add to the great wave of commentary triggered by the 100-day milestone, but I’d like to relay a pithy comment from my old friend Ron Allan when the Trump presidency was a mere 74 days old:

“I’m pondering what will happen when his frustration level builds. He has his list of things to do. So far the record is this:    

• What he has authority to do on his own, the supreme court is blocking.
• What he has to do through the legislature, the legislature is blocking (in spite of both houses and the presidency being of the same stripe).

“If this keeps going, he could resign in frustration. “America does not deserve to have me. I’m not wasting my time any more. etc etc.”

“It is hard to see him lasting. He got the job with the megalomaniac notion that only he can (and will) drain the swamp. If he fails he will not stay. So it’s a race. Which comes first, Resignation or Impeachment? I think the risk of Assassination is receding.”
