I bet you dollars to donuts the hideous system that grinds down the poor internationally to make our cheap shit would still be in full swing, China would still be full of quasi-fascist pricks, your health system would still be a shambles, the terrorists would still have attacked, the privatisation of the human genome would still have occured, the government would still mysteriously care about what two consenting adults choose to do with their genitals, your debt would still be looming over you.
Worst of all, even if Gore did push through massive reform to get serious on global warming at the very beginning of his career (which would have been suicide), China and India still wouldn't care.
Moreover, who knows what scary shit either Kerry or Gore would do to hold on to power and retain "legitimacy"? The government would still expand massively and the possibility of localised decentralisation would shrink just like it always does.
