Chris Clarke talks about his reasons not to vote for Obama next year and in the process creates the best metaphor for US national politics I’ve yet seen:
There are differences between the two parties. Despite the usual straw man, no one — except college students new to leftism and maybe Alexander Cockburn — ever really says there’s no difference between the parties except as the most shortened of shorthand. In point of fact, there’s as much difference between the parties as there is between clockwise and counterclockwise on a ratchet wrench turning a bolt. Turning rightward tightens the bolt. But you don’t want to break the handle by pushing too hard, so you relax and turn the handle back to the left. The wrench loosens a bit, if ineffectually — the bolt doesn’t move, but the pressure eases up. And then comes the next push to the right, tightening the bolt still further. Each cycle has its new status quo, its period of tightening up and release, and the result in the end? The leftward relaxation has merely made the rightward clampdown possible.
