To be clear, MAGA voters are just plain ignorant. They have no idea what Republicans have in store for them. They just love that trump 'owns the libs'. They will soon find out.
MAGA Republicans in Congress, and for that matter all Republicans in Congress want to get rid of the ACA because the pesky 3.8% tax on investment income over $200k/year is evidently a bridge too far. That tax funds the Medicaid expansion, so everyone in the South will now go back to the hospital ED for primary care.
The aforementioned ignorant voters don't even know what ACA means.
Yet.
