Liberal voters don't unite well, and they also tend to have lower trust when it comes to misinformation.
Just to be clear though: the Communist Party of China is not a massive fan of far-right parties, there are certain ideological barriers there.
Russia employed the former left-wing German Chancellor as part of their strategy making an invasion of Ukraine economically viable for them (it is worth pointing out that when right-wing politicians pointed this out, it was received as a crazy conspiracy theory..."liberal voters" distinguish themselves as people who believe themselves particularly unlikely to believe in "misinformation" whilst simultaneously believing in things that make no sense, most people who have a knowledge of politics are required to believe things that aren't true...if they were in touch with reality, they wouldn't vote).
Pretending only rational discourse is valid ways to plan or engage in politics omits a lot of what's important.
