Senate Republicans are hurtling toward a last-ditch health-care vote sometime this week, but they almost certainly don't have the votes to repeal and replace the Affordable Care Act. Sens. Rand Paul (R-Ky.) and John McCain (R-Ariz.) are firm “no” votes, with Sen. Ted Cruz (R-Texas) saying Sunday he's opposed to the bill "right now." Sen. Susan Collins (R-Maine) said she's strongly leaning against the bill, and other opposition is piling up.

The bill in question, the Cassidy-Graham plan, would dissolve ACA marketplaces, slash Medicaid funding and give almost all of the federal money propping up Obamacare to states to create health programs as they wish. Those grants would grow slowly and disappear within a decade. It also would allow states to waive many ACA regulations, such as those that prohibit penalizing people with preexisting conditions. In short, it would get rid of Obamacare and much of the federal government's role in health care.
