this would have been assumed unconstitutional before the hobby lobby case last year. i know it looks like a local legislative issue, but it's really a federal judicial issue.
a lot of companies have come out against this as unworkable, including a lot of what's left of the manufacturing sector there. what they need to do is focus on changing the judicial precedent, by orchestrating a case that forces the court to deal with a contradiction they can't square. it should have to do with workplaces restricting christianity, somehow. that will force the court to reverse itself, which will allow a judicial challenge of this law.
that could take 20 years.
