Allowing insurance sales across state lines comes up perennially as a way to drive down the cost of health care.
Conservatives argue that allowing a plan from a state with relatively few benefit mandates - say, Wyoming - to sell its package in a mandate-heavy state (like New York) would give consumers access to options that are more affordable than what they get now.
Liberals tend to argue this is a bad idea, contending that it would create a "race to the bottom," where insurers compete to offer the skimpiest benefit packages.
