May, easily.

VVD is definitely closer to being classical liberal than populist.

The VVD accept the fundamental tenets of the Dutch welfare state, so no, fortunately they are not at all close to being classical liberal. They are, however, pretty populist.

What's more, populism is not an ideology, it's more of a style (Americans don't seem to get this and I don't know why). A party can theoretically be both classical liberal and populist.
