Broadly speaking, PK is sort of right. The hard right nutfuckery of Reagan's party doesn't exorcise the fact that the EPA is a Nixon gig.
Dictatorships, which often skew conservative in practice if not in ideology, have a far better track record of environmental protection than liberal democracies.

Guess which one of these countries was ruled by a strongman and which one by a (hugely dysfunctional, as is very often the case) democracy.
As far as Obama goes, I think he's doing okay. The creation of an insurance mandate without a public option is monumentally stupid, and my feelings will very quickly turn to anger if he signs a bill that even approaches that. I am also always haunted by the idea that he was, in fact, bought and paid for by the banks. I don't think this is the case, but considering where a lot of his early contributions came from, and the silly putty stick they're swinging around impotently at the FrankenBanks, I would be lying if I said I didn't fear the possibility.
$9 billion in infrastructure money in the stimulus bill is also a crock of shit, especially when you compare it to the $90 billion China pumped into their infrastructure with their stimulus. Education, so far, looks to be a bright spot. People need to quit crying about the unemployment rate. All this jabber about the 'Great Recession,' no shit unemployment is gonna hit 10%. It wouldn't be a global economic disaster if finding a job was easy. The administration is handling that pretty well, I think, by pushing for extended benefits. Unemployment wouldn't be such a massive burden if people didn't have to contend with crushing health insurance rates (or massive debt incurred by lack of health insurance), but I digress. A lot of these jobs that have evaporated were transitory, low-paying deals created under the Bush administration's economic rush to the top (and fall to the bottom, for most people). 2/3rds of the wealth created during those 8 years went to the top 1% of earners. The middle class was squeezed on both sides, and job creation as a function of per capita wealth generation was negative. Employment numbers were based on a house of cards before the banks blew everything up. Employment will recover, don't panic (at least for the next 5 years; it is useful to think of this economic clusterfuck as historically parallel to the panic of 1931, which means that unless Team Obama gets their shit together vis-a-vis the banks, we'll be looking at a real Great Depression within the decade).
