Is the one thing about the Obama legacy that can’t be repealed. Namely this:
There is no mystery about Barack Obama’s greatest presidential achievement: He stopped the Great Recession from becoming the second Great Depression.
Obama did many important things, Obamacare being the obvious. As someone who had seen many failed attempts at achieving this, to see him team with Pelosi and others to achieve this was astounding.
That said, there would have been nothing accomplished by Obama if the US spiralled into a second Great Depression, dragging down the world economy with it. I continue to see criticism of the actions taken by his team then, especially among progressives. They argue that more should have been done. You can google “Obama terrible” and find pieces like this.
Time will tell, but so far Obama is holding up as anything but terrible. I predict he will rise in Presidential standing in the future. Meanwhile, the world is in much better shape due to the actions he took in the early stages of his presidency to avert worldwide economic disaster.
