If politicians believe they will be rewarded for responsive behaviour at the ballot and punished for doing the opposite, they are disciplined to follow-up on the public's desires. That the treat of electoral accountability prompts re-election minded politicians to act in line with the public's wishes, vitally hinges on the assumption that politicians feel monitored in the first place. To understand how this precondition for anticipatory representation works in reality, this article examines politicians' perceptions of voters awareness of party initiatives and parliamentary questions. Quantitative and qualitative survey evidence collected among Belgian MPs (N=164) shows that politicians consider citizens as rather uninformed about politics but, paradoxically, believe that some of them are aware of specific party initiatives and oral questions. Evidence on citizens' actual knowledge shows that politicians strongly overestimate voter awareness. Why is that? From their reflections, we learn that MPs over-generalize feedback they receive from informed citizens, leaving them with a biased image of how aware voters actually are. Also, the exceptionally of gaining visibility with their work causes politicians to overestimate the scope of awareness when they are covered in the media, receive reactions on their social media accounts or simply work on salient topics.
