Republicans vote to defund The Affordable Health Care Act (Obamacare)

I cannot understand this, unless it is becoming more and more obvious that Health Insurance prices are coming DOWN under Obamacare!
Even if they do go up, as Republicans claim, it will because of BETTER coverage. The ACA says that you cannot be dropped if you get sick, also you cannot run out of coverage if you get real sick, also you can keep your children on your insurance until they are 26, also insurance companies must spend at least 80% of premiums on health care - previously they could pay their hundreds of executives tens of millions each and pay huge dividends to their investors, as well as a number of other helpful advantages.
But if it gets defunded, prices will go up because the insurance companies will once again be able to pay their executives exhorbitant salaries, take more profits out, and they will of course stop insuring anyone who gets sick. Or might get sick. Or ever was sick. As well as dropping all the other provisions 
Another reminder, Obamacare is identical to Romneycare which worked just fine in Massachusetts and was a good system - until Democrat Obama stole it!!
Just saying.
