Edwards drops out

Bugger. He didn't have a chance of winning, but if he kept going he was likely to have serious influence, and with his focus on poverty and inequality - something Americans don't usually talk about and Democrats shy away from for fear of being lablled "socialist" (a dirty word in America) - that influence was desperately needed. OTOH, he has already pulled the campaign somewhat in that direction, so he has achieved something by running.
