First of all, the Republican health care "plan" is nothing but an $800 billion tax break for the wealthiest Americans (over ten years). That's it. 

Whatever else they throw out there is simply cover.  They're going to gut Medicaid and its assistance to American seniors, nursing home residents, birthing mothers (50% of them), and poor children by shifting the financial burden to the States, many of which will then simply dismiss the burden outright. 

We're an oligarchy now, in post Citizens United America, and the rich paid billions in the last election to guarantee that the taxes raised by Obamacare go away.  They're so eager for this additional tax relief that the IRS has reported rich folks are delaying tax payments already, waiting for Mitch McConnell to make good on his promise to trade America's health for a bit more wealth. 

No one will be hit harder than Trump's Red State stalwart working class voters.
