"The wellspring of Tory electoral confidence is Jeremy Corbyn... voters sense that the opposition is crawling with cranks and bullies. Luckily for Corbyn, Johnson is striving to make the Tories look even more unhinged and thuggish ... Many anti-Brexit voters have no more patience with Labour and no respect for its leader. But Johnson’s Trumpian excesses make Labour government seem sensible by comparison, even to people who once recoiled at the thought of Corbyn in Downing Street. It is hard to know which of those factors weighs more in a ballot box."Sounds about right. Who, indeed, can tell?
