He's done nothing -- in fact, made it worse. Improving access to health care would invovle things like: training for nurses, training for general practioners, training for specialists, building clinics in areas which are currently under-served. ObamaCare doesn't do any of that!
ObamaCare fiddles with bureaucratic forms, tweaks laws dealing with the insurance industry, and puts overseers behind desks.
There is no improvement in access to health care -- and the bureaucratic nightmares drives good people out of the industry, which results in LOWER access to health care.
But I guess the "experts" don't see much reason to talk about this.
And he/gov't shouldn't!!! The private HC system should be doing that..but they won't for various reasons.
The med schools keep enrollment low for a reason.......more docs and their pay goes south.
