US administrations always make at least lip service to an over-valued (that is, aggressively anti-export) USD ... but in the language of "strong" and "weak", how could you favor "weak"?

The administration actions regarding the long term value of the dollar are, of course, their actions with respect to promoting or discouraging improved productivity. So the Bush administration would have to be judged an aggressive pursuer of a "weak" dollar, via their pursuit of a banana republic economy, while the Obama administration might be judged as a weak pursuer of a "strong" dollar, but quite easily diverted form that policy.

I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
