The GOP tax bill is deeply unpopular, but Republicans still have an opportunity to influence public perception because many Americans know little about it.

The GOP megabill has new tax breaks aimed at low- and moderate-income households, and spending cuts that could make it harder for some to receive public assistance or hold onto health insurance.

Nonpartisan analysts say the wealthiest Americans would see the biggest benefits from the bill, while lower-income people would effectively see their incomes drop.
