In the Citizens United case the Supreme Court held that corporations can spend money to support or oppose candidates, that to limit such spending is an unconstitutional ban of free speech.
The First Amendment says:
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
It follows then that corporations can spend money to support or not any given health insurance program, that to limit or mandate such spending is an unconstitutional ban on the free exercise of religion.
This is an excellent comment! (Excellent tagline, too)
