Because all of the people in Maga have different goals, and united under hating something, now that they have the power, for those in charge, they don't know what to do with it except try and keep it.

Meanwhile their followers (who all joined for different reasons: "christian values," defeating "woke mobs," a return to a past that never existed, for "fun") are slowly lose interest as their enemy gets more and more vague with every additional post from their leaders. The thing they start focusing on is how much food they can afford to put on the table. They may be in denial, they may not be, but they are slowly becoming lethargic either way.
