I know Trump is highly polarising and can be abrasive, but you could also get someone in power who is not abrasive yet does not ruffle the feathers enough to disrupt the status quo. Trump was tackling multiple big issues at the same time, it almost seemed like chaos. Taking on NATO countries for not paying their agreed 2% of GDP into defence, the North Korea meetings, tariff wars with China, the border issue and threats of 20% tariffs with Mexico if they didn't sort it, Germany tariff negotiations, where the Germans were complaining that Trump would stick 20% tariffs on EU cars. This latter point I found a bit galling because the current tariffs for EU cars to the US were only 2.5%, yet the EU was charging 10%! Hypocrites! Obama was very smooth, but maybe when you are smooth, you are not ruffling any feathers and so the change is plus or minus a small amount deviating from the status quo.
Trump is to convention as Uber is to the taxi business. A disruptor.
