Highly likely the tories will win with a fairly comfortable majority. LibDems will pick up pro-EU votes from those with short memories and further hurt Labour who are lost under Corbyn.
At a time when the UK has badly needed an effective opposition, Corbyn has resolutely failed to rally his party. Those on his side - with some justification - claim he's been hamstrung by biased press-coverage and fifth columnists. Others - also with justification - say that a party leader's entire job is to get beyond that stuff and communicate their message despite it. And Corbyn hasn't done that job.
Whether you're pro or anti-brexit; the benefits of having the process scrutinised and challenged by a sensible opposition is surely to everyone's benefit -- though even such scrutiny appears to be tantamount to treason in the new Daily Mail-run UK.
If the tories win a further mandate; it will primarily be based on how they have handled brexit to date (appallingly IMO, but that's me). And it will be an endorsement of that approach.
Heaven help us!
