The executive order Trump plans to sign is being sold as the fulfillment of his promise to allow insurers to sell plans across state lines. But here’s the catch:

The basic idea is that insurers would be able to sell policies in multiple states but only have to adhere to the regulations of their home state. So an insurer from a lightly regulated state, where policies may offer skimpier benefits and lower premiums, could start marketing its plans in a highly regulated state, where premiums tend to be higher…

…it would split the market so that healthier folks would flock to the skinnier plans, while the sick would stay in the more comprehensive plans, pushing up their rates even more.

Bypassing Obamacare regulations means that these plans would provide no protections for those with pre-existing conditions and so would basically turn the Obamacare exchanges into high-risk pools, which are financially unsustainable.

Trumpism.
