Yes and no. Many companies in industries prone to regulation have accepted that the regular see-saw of political power means that roughly half their time will be spent under more stringent regulations, and so it makes more sense to stick with certain regulations instead of changing processes (which carry their own costs and complexities) every few years to shave a few cents on the dollar.
An example: what if a Republican congress repealed legislation banning leaded gasoline? Would gas companies begin putting lead in gasoline again? Doubtful. Not only would it be a terrible PR move - since everybody accepts that lead is a dangerous neurotoxin - but as soon as government switches hands, the lead ban comes back, and all of that time and money switching to lead will have been an unjustifiable waste.
Yes but in this situation we aren't talking about rolling back changes they have made but about not implementing new changes, they are easier to ignore or put off until there is a legal requirement to actually make those changes.

Maybe not the best example, but you get the idea.
