Whatever happens next Thursday, the momentum gathered by Labour in this campaign will continue into the next Parliament and beyond. If May wins, the Brexit negotiations will be such a disaster for the Tories that she could even be out of office before 2022. In fact many people are now saying the Tories realise what a train wreck May is and want to lose the election to give them an excuse to dump her. A few Tory candidates have stated publicly that May has completely ****ed the campaign up.
Corbyn, on the other hand, has got stronger and stronger by the day.
