Hi doma,
Maybe you have forgotten?
Wall Street crash.
Housing slump.
Foreclosure crisis.
Rising healthcare burden.
Dysfunctional and obstructive congress.
Unfunded wars.
Supply side economics.
Bush taxes, which the republicans fought for to a man, whilst pretending the man himself doesn't exist.
Not all issues can be wished away by the president. Some require a lot of work and a fair amount of time.
