Actual conversation on another site when a conservative announced she was disappointed that the healthcare bill didn’t include buying policies across state lines:

Me: So you favor the erosion of a state’s right regulate insurance appropriate to their residents?

Her: I favor competition in the marketplace. States can regulate their own insurance. Then they can compete with the state next door who gets to do the same thing.

Me: But that’s what happens now. Blue Cross or whomever offers a plan in Nebraska that meets Nebraska’s requirements, and one in Texas that meets Texas requirements and so on.

I await her reply. Which could be a while as people come and go, so many discussions aren’t real-time.
