They would look weak. It’s not about policy it’s about being tough on “insert any issue” and letting the fanbase lap it up.
The easy part about running on an anti-whatever policy is that if you keep people on drip fed fear and anxiety it hits a lot more people than it ever would in a content society. A miss isn’t a loss because it just falls on deaf ears for the people who are gonna vote that way anyway. If you are on the other side it’s a hit no matter what, you either agree or are disgusted which inches you just that little bit closer to the fear and anxiety point they ultimately want you at.
Reactionary politics are instant dopamine for everyone.
