The MAGA brand is chaos, cruelty, and lies. Noem is experiencing what will happen to MAGA's when sunlight is shined upon their acts of incompetence, cruelty, and lying.
There is a whole big world outside the MAGA media echo chamber waiting to confront them with truth and facts.
No matter how poorly MAGA's do in free and fair elections, they will never accept the truth - many, if not most, people don't like them and don't want them holding elected office.
