The impact of the U.S. midterm elections on transatlantic relations

In the months leading up to the 2022 U.S. midterm elections many Europeans let it be known that these elections felt exceedingly consequential, certainly more than the average midterm election round. A first indication was that my son asked me in September to remind him how to apply for an absentee ballot. A second indication came during a dinner in mid-September hosted by the U.S. Mission to the Netherlands where it was noted that the Dutch were paying close attention to the campaign.
The big reason, of course, were concerns raised by Donald J. Trump and his possible impact on both U.S. domestic and foreign policy as well as possible knock-on effects to American democracy. The question that I was asked the most: will Trump be the kingmaker for Republicans running this November? And if so, what does that portend for November 2024, when Trump himself runs again, and what impact might that have for the future of American foreign policy?
