With the sincerest of apologies to my revered ancestors, I'd have to anglicize that name, if it were mine.
Understood, but he's in West Michigan. Dutch names around those parts don't sound strange to Michigander ears. If you want really unspellable examples of Dutch names, think things like Rensselaer Broekhuizen or Kees van der Staaij.
Names like that actually get people extra votes from many conservatives. If the choices are Fred Upton or Jack Hoogendyk, a significant percentage of people in the Republican primary will vote for Hoogendyk merely because of his name.
The reason why is an ethnic version of “branding.” Even among non-Dutch people in communities with a significant Dutch Reformed presence, the presumption is that if you're Dutch, unless proven otherwise, you're probably some sort of fairly conservative Christian even if you're not Dutch Reformed, you're very frugal in your personal and business finances, and you're right-of-center politically. Those are good things for a Republican to be identified with in that area — lots of people who know nothing else about you will like you just because of your name.
Of course, there are also negatives to being Dutch. The perception is that you're religiously narrowminded, are part of a pretty ethnocentric group, and are so strict about money that you pinch pennies until they scream for mercy. However, the people who don't like those things probably wouldn't have voted for a strongly conservative Republican anyway.
To be clear, I'm writing as a Grand Rapids native and Calvin graduate who doesn't have a drop of Dutch blood but is a right-wing Calvinist and therefore even stricter than the Dutch stereotypes of such things. I was one of the very few non-Dutch people attending Calvin back when I was a student, and I routinely had people do double-takes when they saw a rare non-Dutch name that didn't have distinctive Dutch suffixes or prefixes like VanderSomething or DeSomething or Somethingstra or Somethingsma or Somethinga.
