Parties adopt online participation methods in the hope of engaging a wider group of participants. However, literature on the digital divide suggests that this is unlikely to happen, as online participa-tion remains dependent on the same factors as offline participation: income, class, education. Based on a mixed methods study of members of the Green Party Germany, this paper discusses the expected and actual effects of online participation tools on the participation of party members. Expectations are that these tools will benefit nearly everyone, but in practice, the goal to engage inactive members is only partially achieved: Younger members and those with lower educational attainments are mo-bilised, but women are not. These effect differ depending on the type of technology. I argue that this is an expression of the prevailing digital divide, which needs to consider not only a socio-demo-graphic divisions, but also the multifaceted effects of different technologies.
