As a PolySci major form an Ivy, and a professional Economist, I really think Obama has continually failed at these debates. He hasnt really staed what his plan is, where the $ comes from and so on. Also his economics completely fail. They seem nice and fuzzy, but every time his economic policies, and things like his plan on health care, they have failed.
Hes a socialist, and, historical, he loses. when we look to pure logic, we can see that his platform fails. Granted, I don't support McCain(I am a Libertarian) but Obama would be a worthless president. Obama's plans have waaaay too many exceptions. Plans like that are always exploited, and cost the upper-class(the ones who have the biggest power to fix the economy, its a fact) to have their taxes raised.
