It's a fairly simple point, really-- Obamacare was a set of regulations on the health insurance industry that made health insurance: 1. Much more expensive, for 2. Less coverage (higher deductibles).
This is not disputable on the facts. Just do a basic internet search to find out what's happened to insurance premiums over the past few years, read something besides the New York Times, or talk to anyone who's actually had to buy health insurance on the individual market in the last few years in the US.
But hey, not everyone is capable of learning, or of empirically-based reasoning. No need get defensive about it. You may carry on with the feelz now.
