Thats a question for idiots, way too simplistic. A president does not completely cause a recession. This recession is because of the collapse of the financial markets and the banks. Fault the democrats for ignoring warnings by congress and because of the program that forced lenders to loan to people that weren't qualified, fault the republicans and Bush for not enough oversight of the banking system (along with Barney Frank), fault Americans whose culture has changed for the worse, fault Bush more for wasting our $ in Iraq and fault Obama partly for the recent drops because he is pushing a socialist system that wall street doesn't like and is promoting the largest deficit spending we have ever seen.
