If I worked for Mastodon, I would create a turn key solution for parties that want to set up a Mastodon server for all their party candidates.

Ilhan Omar is still on X.
Bernie Sanders is still on X.
AOC is still on X.

Make it easy for them to switch. Then make sure they are aware of this option.

Update: The first part already exists on

as pointed out by @osma. Thank you Osma.

Managed Mastodon

@randahl yesterday at FOSDEM there was a member of the European Parliament who was asked why so many politicians are still on X and her answer made total sense (sadly):

Politicians stay on X because journalists are still there, so they feel that if they leave they will become irrelevant / not be written about.

And journalists stay on X because politicians are there.

It’s a vicious cycle

@_elena however, there is only one answer to this dilemma: politicians must take the lead. Journalists can only go where politicians already are.
