Labour had a fully costed manifesto, its headline policies largely funded by tax increases on the very wealthy and by increasing corporation tax.
The Tory scum, on the other hand, had fucking nothing but promises of more austerity for the average joe, more tax breaks for the rich, and pissing off their core demographic with threats to their homes and pensions.
They're a busted fucking flush, whereas Labour are in a strong position to carrry on the momentum built up and destroy them next election, particularly so if the Tories spectacularly fuck the country up as they're well on course to do!
