Let’s take it as a given that the United States is the world’s preeminent nation state and that the U.S. president matters a great deal to international affairs.
That said, there are three BILLION people in China, India, Indonesia, Japan, Malaysia, and Singapore (where I live now) that likely don’t care what the three MILLION people in Iowa think will make a good president.
And for that matter, I don’t think I do, either. Well, not more so than any other group of Americans.
