Since a hospital cannot turn them away under the anti-dumping laws, the next and most logical solution is to close the doors. I am sure the government at some level will try to make them reopen.
What they're doing is putting Prop 86 on the ballot. It would raise the cigarette tax by $2.60 a pack (bringing the cost of a pack to about $7), and use a big chunk of the money to "fund emergency room care" (i.e. give medical treatment to illegal immigrants).
