Yep Obama caused the housing and debt bubbles.
It's not what caused anything.
No matter where you are going, your only option is to proceed from where you are. The Big 0 campaigned saying that it was the worst economy since the Great Depression. It was no surprise to him unless he is a lying SOB with no integrity and no honor.
That he inherited a bad situation is not in doubt. That he made it worse is not in doubt.
What is in doubt is what can be done to correct it. There is doubt on this because the Big 0 has made no progress and in truth has hampered the recovery at every turn.
If he was a foreign enemy he could not be doing more harm.
