  With a network approach, we examine the case of the German far-right party
Alternative f\"ur Deutschland (AfD) and their potential use of a "hashjacking"
strategy. Our findings suggest that right-wing politicians (and their
supporters/retweeters) actively and effectively polarise the discourse not just
by using their own party hashtags, but also by "hashjacking" the political
party hashtags of other established parties. The results underline the
necessity to understand the success of right-wing parties, online and in
elections, not entirely as a result of external effects (e.g. migration), but
as a direct consequence of their digital political communication strategy.
