I suppose you're German and you're familiar with the failed attempt of Friedrich Merz trying exactly that with his CDU?
The trick populists use is that you make something seem to be something everybody would want, of course, and demand for it to be implemented, without having actual solutions.
How do you address a party demanding that the government should stop poisoning citizens with chemtrails? [1]
Would you agree that Germany needs to restrict "uncontrolled immigration"? I would. Who wouldn't?!
But wait. What's "uncontrolled"? Who gets to decide on the definition? If we had a definition, do we actually have uncontrolled immigration, and if we do have it, what exactly is the problem with it, and why would we want to solve it?
But see, they're not in the problem-solving business. They don't care. They're in the "stir up fear and promise we have a solution" business, which is a very successful business model.
If 20% of your population believe that there's 5G in your vaccine and the government wants to kill half of your friends, you need to fix other things, like lack of education.
A ban on a malicious actor trying to game the system might be a temporary hack to win time.
