I've never quite understood the 'omg if we elect Trump it'll be so embarrassing' line of thought. I mean, consider the facts and the countries. Russia - ruled over by illiberal strongman Putin; China - a dictatorship; India - a country whose current Prime Minister is a Hindu Nationalist; Japan - has a cabinet composed primarily of historical revisionists often ill at ease with the idea that Japan committed any war crimes in World War II at all. Look at Europe, where in many countries the parties of the moderate middle are headlong decline/retreat - an FPO candidate stands a good chance of becoming the next Austrian President and Marine Le Pen is pretty much guaranteed a place in the second round of next years French Presidential Election, whilst hard right parties in the Netherlands, Sweden and Germany continue to gain considerable ground.
Really and truly, is Trump that embarrassing a leader in this context?
Yes. Simple as that.
