I wonder, those who supported Trump because they hate big federal government favoring states rights will think when Trump/Pence & the Republicans decide that States have no rights in determining which insurances can sell into their state & what the policies need to cover.
U.S. Constitution
Article I, Section 8
"To regulate commerce with foreign nations, and
among the several states, and with the Indian tribes"
The so-called "Commerce Clause", Part of the original purpose of which was to delegate the authority to the Federal Government to
eliminate trade barriers between the States, i.e. in this case, knock down internal state barriers to selling insurance ACROSS STATE LINES.
It's actually an exercise of the clause that aligns with the original intent.
