You're asking the wrong questions.
Your questions should be:
What was the extent of the adverse effect republican foot-dragging had on the economic recovery?
Given the fact of republican foot-dragging, can an accurate assessment be made of the Administration's economic policies?
Do conservatives understand that the Administration's economic policies can only be comprehensively implemented with the co-operation of Congress, something Congressional republicans have refused to do?
And can there be an accurate, objective, non-partisan assessment of the president's economic policies well before the end of his time in office.
The last question is rhetorical, as of course its answer is 'no.'
But that's no different for any other president. When Bush took the WH, Clinton's economy had hit the trough that Bush had to reverse. Then Bush got hit with the impact of 9/11 on the economy. I never see a liberal explain how that unfairly weighed on Bush's numbers. And anyone who says it was a 1% quarter impact is way off.
There were people who were worried that because it hit when we were so heavily leveraged during the trough of a business cycle that it almost collapsed us.
No one makes excuses for what Bush had to do to recover not only economically but to combat an enemy. That's never discussed.
The thing is.....yes, we were pulling out of a crisis and a recession when Obama took the reins...but on the other hand, there were signs we were starting to recover from the recession only a few months into O's tenure.
The other problem is that Reagan inherited the nastiest economy ever and he turned it around to firing on all cylinders.
