Trump's new push for selling insurance across state lines

How it works: Critics see this as a backdoor way to deregulate insurance. If a patient in New York can buy a lightly regulated policy from Iowa, what good are New York's rules about what plans have to cover and how they have to cover it?

• There are logistical hurdles: It's pretty hard to set up a network of doctors and hospitals that will work for patients in both Iowa and New York.

Between the lines: The administration already took a bit of a victory lap on this front when it expanded access to association health plans.

• That wasn't a full-scale deregulation, but it did expand of a type of insurance that can cross state lines — even though, due to the difficulty of creating provider networks, those plans are generally confined to one metro area.
