I really don't think this deserves an answer but here goes.
When Obama came into office in January 2009 we were in the midst of the worst financial and economic crisis since the Great Depression. The unemployment rate in January 2009 was 7.7%, having risen from 4.9% just a year earlier. It would continue rising rapidly before peaking at 10.1% in October 2009.
Both Obama and Bush in 2008 recognized the need for fiscal stimulus and large fiscal stimulus programs were enacted under both of them. I think in both cases some of the details of their fiscal stimulus programs were not optimal. But they were correct in diagnosing a need for massive fiscal stimulus. I think probably the largest mistake in fiscal policy during the Obama years took place from 2011 to 2015, when fiscal stimulus was withdrawn prematurely. I'm not going to try to apportion blame for that, except to make the observation that the Obama administration and the Republican controlled Congress could have done a lot better. To remove fiscal stimulus at a time when the unemployment rate was still very high and the economy struggling to gain traction did not make any sense.
In spite of those mistakes, by the end of 2016 the unemployment rate was down to 4.7%. Since then it has fallen further to 3.7%. Growth has accelerated in the past year, in part due to fiscal stimulus (mainly tax cuts). This has blown a $300 billion hole in federal finances. It is not hard to gin up the economy when you blow a $300 billion hole in federal finances. The question is whether it is wise. Fiscal stimulus is a good thing when unemployment is high. It is not such a good idea under current circumstances. Interest rates are rising, in part because of the high deficits and in part due to concerns about a potential rise in inflation.
Whoever is elected president in 2020 will have to grapple with the damage done to federal finances by the policies enacted in the past two years. It won't be fun cleaning up the mess.
