The Tories are responsible for the referendum, the negotiations following the referendum, the infighting in their own party and the austerity of the past eight years. They have had three terrorist attacks and numerous failed attacks during a time they've cut police and military funding and they are planning to make even more cuts. They've reacted to a worsening climate here and globally by encouraging fracking, at a time when gas prices are historically low. They've have a foreign government try an assassination on our soil, which murdered a British citizen, and have reacted to it by not pnly not banning the main way that foriegn government has its favoured citizens get into our country with their money, in fact aside from kicking a few diplomats out its almost impossible to detect any response from them. The NHS may well collapse this winter, debt (private and public) has ballooned since 2010 and the first warnings have gone out about the start of the next financial crisis.
If the average voters reaction to all that is to fall for the lies, half-truths and misleading statements of the media and the Tories against the only opposition they face, then they are idiots.
