Who are the corporate backers that supported expanding medicaid in the ACA? They didn't agree so who was on which side?

If you want to talk about the 2008 financial crisis, ok. Why did Dodd-Frank pass? Why did the corporate backers allow for the creation of the CFPB? How is it that only once Trump came into office did it stop doing its job?

You are asserting that there is a cabal of corporations controlling politics in the USA, what do they actually agree on specifically? Why have things in many instances actually changed when administrations change?
