The most astute observation I've heard in recent years about this subject came from a human resources expert at an industry conference I attended. He said the problem with today's political process in the U.S. is that the two major parties are aligned in a way that made sense 40+ years ago when we were an industrial economy, but don't make sense anymore. Now, you have an upside-down scenario where the Democrats are the war-mongering corporate globalists and the Republicans -- only by default, not by principle -- have become more of a nationalist/populist party.
Indiana and every other state contemplating such legislation ended up watering it down to the point that it became nearly meaningless. The Country Club/Corporate war-monger class is drifting over to the Democrat party if they can't staunch the Populist/Trumpian rise.
Neither party has any core beliefs. They never really have. Their belief is the party. Increase the power of the party. They have a base they pander to for those core votes, but it’s lip service.
