Which is why he spent a whole very important year on his healthcare fetish/bungling, that really needed to be spent on national and global economic reform....a project that never even got started, not really.
I encourage you to put in more thought so that you can avoid looking as silly as you do here.
Obama did give up vast amounts of political capital in pushing hard on the ACA. He did not give up much else though. We needed a steady approach after pulling out of near disaster, not some balls to walls lets try to push this economy to the limit approach and he very likely knew the past results of mid-term elections in the first term of a Presidency. In other words, he had two years to do something big that he felt was important and he did it, having steadied the ship from going up on the rocks of disaster coming into office.
As for who is most responsible for that mess, its Alan Greenspan and both parties have a piece of him since he switched parties in I think 2007. The CFTC chairwomen was the only regulator that had a legitimate piece of the derivatives mess that was actually at the heart of that disaster that saw it coming and was willing to go after it. Greenspan warned her that if she did not cease and desist, he would have her fired and would make sure her career was ruined, that she would never work again. He was as you might guess a Republican at the time.
Perhaps you should do your homework better.
As for the general topic of Obama, he was not IMO a great president nor even a good one. He was if anything a decent republican president or tried to be as most of the policies he brought forward were policies from Right wing think tanks like the Heritage Foundation. The basics of ACA came from the Right as did Cap and Trade. The GOP would not help pass or even consider policies that were actually born in their own think tanks. That said, Obama tried too hard to compromise and then failing that turned to Executive Order. I consider his presidency a failed presidency on the whole for four major reasons:
1) the aforementioned overemphasis on compromise
2) overuse of Executive Orders
3) not a spirited enough effort with regard to judgeships
4) the utter lunacy of running for a 2nd term without the fortitude to carry his party at least into the House with him. Six years without the House is an unfathomable failure IMO
i don't consider his economic policies a failure. Look at what we are getting for throwing gasoline on the economy. Do you really think this stuff will yield something lasting? Do you not see the risks inherent to throwing gasoline on the economy with little actual return for it. This economy has structural problems and none of what trump is doing addresses those. That is why we are getting such little GDP improvement out of all this gasoline.
He might have recovered the whole thing if he had convinced John Boehner back to the negotiating table to get a budget done in his second term. It cost Boehner his position as GOP leader in the House. But Boehner did not come back and actually lost his position in House leadership as punishment from the GOP for even considering working with Obama to get a budget
