The man owns twitter ffs. The only way his attempts to gain political influence will ever fail is if the UK government block access to twitter or British people decide to stop using it. Until then he has significant capacity to sway political opinion.

As an example: there is significant power in cultivating the default UK experience of twitter for new accounts, which he's already had significant impact on by culling Twitter's internal moderation team. I've experienced it myself and its a an absolute disaster zone of disinformation and bot accounts trying to stoke internal divisions.
