It's early, so withholding too much judgement makes sense. But damn, so far it looks like a shitty version of Obamacare. Many with pre-existing conditions will be discriminated on (granted smokers are discriminated on now, but that we all understand). Medicaid is kept intact, though it's partially castrated by block grant meaning inevitably states will raid it thereby cutting Medicaid health insurance and transferring the cost to the poor, i.e. those who can least afford it. It'll repeal taxes and mandates, which means increasing the deficit. I suppose they'll say it'll magically increase economic growth, but the reduced health inflation and increased job growth we've seen since ACA makes that argument specious at best. By now all the worst ACA predictions have fallen to the wayside.
Basically, until this gets out of committee and passed by either Congress/Senate and scored by the CBO (which hopefully doesn't use some bullshit dynamic scoring nonsense to rate it), it's just more posturing without very many specifics.
