It's a longer term play. If 40% of the populace is committed against MAGA, and 40% is irredeemably invested in MAGA, that leaves 20% so out of touch with current events they haven't formed any strong opinion. Yes, the MAGA administration is going to do the bullshit anyway. But feeding into the "both sides are the same" narrative might tip the balance of voters into re-voting in the bullshit doers.
