The financial industry, among others, provided funding to Obama's campaign in 2008, amidst an economic recession. He bailed out the financial industry, not a single banker went to jail, and the regulations put in place (Dodd-Frank) were insufficient to prevent another crash like the last.

Oh, did I mention those same politicians most in favor of the ACA are bought and paid for, via campaign donations, by the pharmaceutical industry?
