I can see what BoJo is trying to do with this people vs parliament/establishment thing. I think a significant proportion (presumably leave voters) will buy into it and it will be backed by the Daily Mail and the Sun etc..., but Corbyn (for all his faults) was correct to say the establisment is actually the Tory front bench and many many people realise this, so I think the people vs establishment could backfire (if there is an election soon and BoJo is still PM).
I agree Corbyn is hopeless. I think Labour would be miles ahead in the polls if somebody like Starmer was leader. That said I don't think the polls are going to matter a huge amount at the next election as there is going to be a massive push for tactical voting and I think the Tories will be in trouble - and particularly I wouldn't be surprised if BoJo himself loses his seat. I expect the SNP and Lib Dems (in England) to pick up a lot of seats. Quite where Farage fits in I am not sure, surely the Tories will need to do a deal or they will be truly fucked if they have not delivered Brexit (which they won't have) by the election.
