When your constituents believe everything you tell them, such as nothing your opponent says is true, you can take your opponent's policies and claim them as your own while telling your constituents that your opponent never had those policies, like no tax on tips. The people who weren't going to vote for you still won't, and you've entrenched your base enough to prevent them from waking up and voting against you, because to them, there is only one choice: you. No matter who.
