We need all 50 or at least a majority.
This is the one issue that needs to be puched. The failure of the FEDs Bush and Zero have driven up State cost enormously.
This has to have some sort of Constitutional element that would force the issue.
In fact, if the supremes rule that the forced payment of ins premiums is unconstitutional. can an argument be made that the Feds are FORCING costs on States by refusing to enforce the Constitution and the immigration laws?
