I’m going to take a somewhat different tack to describing this.

There are many ways to motivate large groups of people. You’ve likely seen this a lot and not really noticed or paid attention to it. Some examples are tribalism (“Hey! They’re not one of us!”), nationalism (“Those dirty foreign people!”), religion (“Do what I say and go to heaven!”), money (“Do this and I’ll give you something valuable”), etc.

One of the best motivators is fear. (“Do this or I/they will do something you really don’t like”).

Political groups need something to motivate large groups of people. When done well, they appeal to the better sides of humanity. When done by the lazy, the dumb and the craven, they go with the simple one: fear.

That’s what Conservatism has been hammering for a while now. They don’t really have a way to appeal to people’s better sides, primarily because their platform isn’t to make humanity better off. They platform is to make a few people better off to the detriment of everyone else. So they try tribalism (“Those brown people are trying to take your money!”), nationalism (“Those foreigners are taking your jobs!”), religion (“Those non-Christians are trying to install sharia law!”), etc. The most effective one is still fear. So getting their followers scared and angry is the best way to motivate them, get them to stop thinking rationally and build moats that will isolate them from people that might talk them down.

This is used to motivate people to vote in certain ways, as well as motivate them to watch advertisements. In other words: money and power.
