Here are the facts on just how much control we had in 2008-2009:
Obama had control of the House from 2009-2011, but guess what, legislation does NOT become law without the Senate
The Senate operates with the 60-vote-requirement filibuster rule. Total control of the Senate requires 60 votes.
In January 2009, Democrats had 57 seats, with Sanders and Liberman caucusing with the Democrats for 59 votes.
That 59 included both Kennedy and Franken. Franken was not officially seated until July 2009, and Kennedy had a seizure in January 2009, and never returned to the Senate to vote, so the actual number was 55 plus two independents which makes 57.
It was during that time that President Obama was able to pass a stimulus package, but only because 3 republicans, Collins, Snowe, and Specter voted to break a filibuster guaranteeing its passage
In April 2009, Specter became a Democrat, Kennedy was still at home too ill, and Franken was still not seated in April 2009
In May 2009, Byrd got sick, and didn't return to the Senate until July 2, 2009, and Democrats still had only 59 votes Kennedy's seat was temporarily filled by Kirk, but not until Sept, 2009
It was then that Democrats had at least potentially 60 votes in the Senate, and it lasted all of 4 months, from Sept 24, 2009 through Feb. 4, 2010, at which point Scott Brown, a republican was sworn in to replace Kennedy
The only thing the Democrats had control of for two years was the House, and for only 4 months did we have total control of congress, and it was during that small time frame that the ACA was passed

The question I see come up periodically is why didn't President Obama push for a public option or Medicare for All.
The answer is actually quite simple. BECAUSE WE DIDN'T HAVE THE VOTES
Lieberman, Nelson in Nebraska, Nelson in Florida, Blanche Lincoln, Bayh in Indiana made it very clear they would not vote for a public option or Medicare for All
