Obamacare was largely written by conservative think thanks years ago and pushed by the insurance industry, as it acts as a massive forced subsidy to them, for years leading into the passage of the ACA.
Interesting, since one of its inevitable structure consequences, when implemented, will be pretty much the destruction of the private sector insurance industry. "Obamacare" is textbook cultural Marxism, E; its a classic incremental "long march" strategy who's purpose is to gradually force employers to drop their employees from their own programs, and citizens to abandon private insurance companies as the price of insurance goes into the stratosphere. At that point, the only alternative, if one wants to be insured, will be the government exchanges (which will later morph into a full-fledged national health service).
"Obamacare" wasn't "written by conservative think tanks" but by leftist Democrats, the core concepts having been fleshed out by Robert Creamer in his book Stand Up Straight! How Progressives Can Win, published in 2007. The nuts and bolts of the plan come, most likey, from soem of the big names among the Democrats in the House and Senate, but we probably won't know until hell goes into its next major glacial period.
As to the leftist meme that the Heritage Foundation created the initial idea years ago, as with most memes on the Left, it is, as a whole, a frank deception:

I'm not in full-throttle defense of Heritage here, as I think a much more comprehensive free market system in which the federal government is substantially removed from the funding, subsidy, and provision of medical services and market forces are allowed a radically greater influence on the provision of healthcare services, is called for. However, the reality of the old Heritage plan, from the 1990s, is substantially more nuanced than your blanket statement implies.
