President Obama:

… when Social Security was passed, it applied to widows and orphans, and it was a very restricted program … But the point was that we had created a framework that allowed us then to continue to make progress. That’s what we’ve done over the last 18 months. That’s what I expect we’re gonna keep on doing.

See David Catron’s post & video link:  Video: President Admits Obamacare Bill Is A Trojan Horse For Single-Payer.

Writes Catron:

ObamaCare [HR 3590] was the Trojan Horse we always believed it was.  As I tried to remind everyone with this series of videos showing Obama and his accomplices praising single-payer, the goal has always been government-run health care.
