Thanks for chiming in Marengo. Mr. Wilders is, to put it lightly, a bit of a mixed bag. One would think being a party of the right he would support the Monarchy but he very clearly does not. In fact, many of his policies aren't exactly "right-wing". His policies are all over the political spectrum, some good and some bad. Much of his language, personal belief's, and campaigns are atrocious. Whether or not he will be able to form a coalition and be PM remains to be seen.
There are many, many issues facing the Netherlands. The Monarchy is an easy target but getting a majority of MP's or political parties to agree on a course of action for the Monarchy will be difficult. Unfortunately, attacking the Monarchy and other established institutions is a great distraction and populist technique.
