The Christian Democrats in the Netherlands and other European countries are pretty much centrist parties. The dutch VVD is the most pro-free market party in Europe and the closest ally that American Libertarianism could find here. They are truly very pro-small government.
Mark Rutte disagrees with Wilders mostly on economy:
“The problem with Wilders is that he is quite left-wing on the economy . . . while at the same time we agree with some of the measures we could take on immigration in the Netherlands. We disagree on this issue of Islam.”

Interestingly, Wilders have already dropped his demand to not raise the retirement age, which was seen as a major stumbling block towards establishing a right wing coalition:
“’It is a very important point but not a reason to wreck a [potential] cabinet,’ the leader of the anti-Islam party told reporters.”
