1. He's a more powerful speaker & communicator than 99.9% British politicians. He's at least as good as Trump, maybe even better.
2. Populism is on the rise throughout the West.
3. The British state is about to fall off a fiscal cliff. These current years may be seen as the good times by the end of this decade. It's no coincidence we got Thatcherism only after the IMF became involved in UK govt finances. It took the disastrous 1970's for the UK to vote for Thatcherism.
I may easily be wrong and Tate does little in British politics. Im not sure he's a man suited for long term political commitments. However, everything is in place for him to destroy the political status quo if he decides to make a serious effort. Someone is going to upend it all we just don't know who yet.
If Trump can seriously undermine the US political system then Tate has the potential to at least massively disrupt UK politics.
Edit: oh, and we now have Musk's X. UK political news just became largely unanchored from the BBC, Sky, Guardian etc.
