What would happen then?
One could imagine a scenario in which Brazilian President Jair Bolsonaro rushes to congratulate the "re-elected" U.S. president on election night, followed by Saudi crown prince Mohammed bin Salman, North Korean dictator Kim Jong Un and maybe even Russian President Vladimir Putin. Soon, though, the first congratulations from Europe might find their way to the White House, from Hungarian Prime Minister Viktor Orbán, for example, or his Polish counterpart Mateusz Morawiecki.
Should a constitutional crisis in fact develop in the United States following the election, there are widespread concerns in Europe that the EU could once again be deeply divided.
Presidential elections in the U.S. are always tense times for foreign policy experts in European capitals. Foreign Ministry staffers run through various scenarios for what the election result might mean for their country and for the European Union as a whole. The platforms of the two candidates are examined for commonalities and potential pitfalls, for areas of convergence and places where discussion might be fruitful. It is all quite routine.
