Obama has had a breathtaking first 100 days as President. Is he trying to start tackling all the major problems that the Bush administration ignored for 8 years? Could be. The worst Recession (very probably the direct result of Bush administration policies and lack of government action) since the Great Depression has clearly made such a breathtaking pace necessary.
But don't listen to me. Robert Reich has an excellent post in which he describes many of the Obama initiatives and lays out some of the most risky balancing acts that Obama is having to take.
It's a very good compendium of where the Obama administration is right now. Go read it.
