Trump campaigned on these promises about health care: 1. No one will lose coverage, 2. No cuts to Medicaid, 3. No one will lose coverage, 4. Nobody will be worse off financially, 5. Get rid of artificial lines, 6. Everybody's going to be taken care of.

The bill he and Ryan are now supporting breaks most if not all of his promises. The key question is whether his core of misinformed voters will be more upset if this passes and gives them crummy health care, or would the rather keep the moderately good health care they have now and reject Trump and his  support for his vote for this bill,.
