Furthermore, if Halbig holds, the Employer Mandate will only be triggered in those states that have established their own exchanges, meaning that the people in mostly Democrat-run states will be yelling the loudest, telling their governors/legislators to dump their state-run exchanges so they, too, can keep their employer-provided insurance.
