I don't know, it sounds pretty coherent. The statistics look bad for Obama when you put it like that. What do you guys disagree with exactly?
He criticizes Bush for weakening the dollar, but doesn't note that the value of the dollar has been trending upwards since before Obama took office. (Unsurprisingly, since China wants to export to us much more than we want to export to them.) This is not surprising, since we're in a liquidity trap -- which is caused by fear of deflation, not inflation -- and our inflation rate is below the Fed's target. All the money the Fed "printed" went right under people's mattresses, affecting the value of our currency not at all. The abnormally low yields on US treasury bonds relate to this -- if buying a treasury bond is a worse investment than filling in the Gulf of Mexico, then why are people buying them? They must either have an interest in the dollar (China), or fear devaluation of any real asset investment -- in other words, deflation (which, looked at a certain way, is just a devaluation of everything in the world except the dollar). Thus his inflation fearmongering is simply nonsense. If he were accurate, people would be rushing to invest in American assets right now, since our inflation rate is 1.5%.
Similarly, the reason he says it's not economic magic that cutting investment taxes will spur investment is because there's no actual economic evidence that this is true. The stuff about Bush tax cuts is concern trolling, since Obama's plan essentially extends them for everybody -- the top bracket increases aren't that meaningful in any practical sense, it's just ideology. The stuff about raising taxes on small businesses is simply false.
All the stuff about how the economy is still fucked is pretty much accurate, but there are no actual logical threads connecting that information to his argument -- it's just kind of there, and then he asserts that it's Obama's fault, and sidesteps to the worthless inflation/capital gains arguments. Most people would agree that the economy is in a poor state (although it's growing at a normal rate, it's just below the trendline), but the solution to that is more stimulus -- the "dark cloud of reemerging Keynesian influence" he cites.
Here's a comparison between American economic growth and the UK and European Union, both of which have adopted more austerity measures (the tax and spending cuts he advocates).
Here's the CBO's projection on the effectiveness of the stimulus. We just need more.
