People start so many threads because we have never had a major politician, let alone a Prime Minister, as narcissistic and amoral as Boris Johnson.
I'll admit that I'm biased. I've hated the Tories since I was a teenager in Thatcher's Britain. I'm a paid up member of the Labour Party and also have a lot of respect for the Green Party.
BUT when even Johnson's former colleagues admit how worried they are by him, when a senior diplomat resigns because they can't face lying for him any more then you know there is a problem. There are Tory grandees who have devoted their life to the Conservative party who are asking people to vote tactically to get rid of Boris Johnson.
Other politicians in all parties will stretch the truth, put a spin on events, try to avoid awkward questions and repeat the party line even if they don't really believe in it. But none of them tell out and out lies the way he does. When people say "they all lie" that really isn't true. They may overpromise in the run up to an election. They may fail to fulfil all of their commitments. But very rarely do any of them tell actual lies. And none of them do to the extent that Johnson does. He's got sacked from more than one job because of it.
I don't think Corbyn's handling of anti-semitism is comparable either. He may have dealt with it ineffectively, but he is not anti semitic himself (there are videos going back decades of anti-racism and anti-anti-semitism speeches that he's made).
Johnson, on the other hand has made racist, sexist and homophobic comments himself and has never apologised for any of them.
What worries me most about Boris Johnson is his populist, anti-democratic tendencies. He is straight out of the totalitarian handbook (watch the BBC documentary on The Rise of the Nazis or google Hannah Arendt).
He chucked Conservatives who opposed him out of the party, preferring to lose his majority rather than allow dissent (even though he voted against Theresa May). He unlawfully prorogued parliament because he didn't think that the legislature should be able to hold the executive to account. He paid lip service to obeying the supreme court judgement but made it clear that he disagreed. He chose to call an election even though Parliament had given his withdrawal bill a 2nd reading, because that was preferable to allowing the bill to be scrutinised properly.
He banned Daily Mirror journalists from the campaign bus because he doesn't want scrutiny. His campaign has included altering a Good Morning video to make it appear that Keir Starmer was unable to answer questions, and renaming a Conservative Twitter handle to make it appear to be an independent factchecking site.
Page 48 of the Conservative manifesto is particularly worrying as it shows that he wants to make far reaching constitutional changes, no doubt to allow greater powers to the executive.
It's telling that a party which has been in power for 9 years is asking people to vote for it on the basis of what it's going to do in the future rather than on the basis of what it has achieved in the last 9 year.
