Who knows mate, who knows. My personal hope would be that the conservatives take on board the messages that can be drawn from this result and modify their manifesto to be more in line with what the majority want, i.e. an easing off of austerity and more emphasis on looking after the poor in our society and our public services. And if they did that, AND had a leader competent to take the message forward, they could win and win well.
It seems incredible to me that after 15 years of Labour successfully camping out in the middle ground with Blair and Brown (i.e. showing everyone how it should be done with 3 successive victories), the Tories still thoughtplaying to the right and taking on UKIP was the way forward? When May took over she made all those speeches about being there for everybody in society, including the poor, and her popularity shot up enormously. Bizarre that she forgot and instead decided to piss them all off.
But you're right. We could be in an era with two opposing sides, each entrenched in mutually incompatible positions, and neither able to get a majority.
