Finally, you give me something to sink my teeth into...
Your claim was that Obama's policies "made things worse", which is what I'll focus on. Now, first of all you're right on one thing - Obama promised 8% unemployment and unemployment is over 9% right now nationwide - but the stimulus policy did in fact have a net positive effect on the economy - and yes, that means what I'm saying is that without the stimulus unemployment would be even higher.
According to Bloomberg, the Obama stimulus saved or created as many as 3.3 million jobs; that makes out to a 1.8% decline in the unemployment rate compared to what it would have been without the stimulus (so it would've been over 10%, obviously). During it's peak (a three month span through June 2010), the Obama stimulus added between 1.7 percent and 4.5 percent to the GDP.
Now, the biggest problem with the Obama stimulus is that it was A) too small and B) was poorly built (40% tax cuts and a bunch of government aid... it should've been mostly infrastructure). Keynesian economists told the administration that 1.2-1.5 Trillion was needed to close the
output gap(bolded for importance) and reach full employment, but Obama made a political calculation (a smaller package so that it could make it through congress) and that calculation has cost us dearly.
The Republican policy is officially "anti-stimulus" - and Austerity will only continue to make the global economy worse... Which only makes them much worse. And if you like, I can back up that claim - unlike you.
