Idea for a social network:

You can only follow elected or to be elected politicians. A follow means that you get a note stream from them about their speech and action collected by the platform. The politicians don‘t have to be on the platform (but can).

An unfollow means that you are tired of their BS. When election day comes, you can have a look at who you follow (and maybe whom your peers follow). The left-overs may be suitable candidates to actually elect.
