Previous research demonstrated that voters for the Dutch radical right party PVV were the most stable voters among the highly volatile electorate. However, since 2017 two new radical right parties have successfully entered the Dutch Parliament: Forum for Democracy (FvD) and JA21, conceivably at the expense of the PVV. The success of these new parties is puzzling, because there does not seem to be much room for new parties campaigning on a highly similar platform. In our paper, we use LISS panel data to study the determinants of vote switching patterns between four subsequent elections from 2017 to 2021. We find that the surprise victory of the new far right in 2019 can be explained by its ability to attract both former PVV voters as well as voters new to the far right. Since then, FvD has lost many of its supporters again, but these voters have mostly switched to other far-right parties, meaning the far-right support base has become fragmented, yet enlarged. This suggests that when provided with viable alternatives, radical right voters are as volatile as other voter groups.
