He will.
Tories need to start listening to their own voters if they are to stand any chance at the next GE. Pollsters who ran focus groups in both by-election constituencies have said that the biggest issue raised by Tory voters who no longer intended to vote Tory was still Partygate and the fact that Boris Johnson is a proven liar and law-breaker. Not just lying to the electorate, but to his party, their supporters, the house and the Head of State.
Some deluded and mostly twitchy-ringed red-wall Tory MPs are still hoping against hope that Boris still has the x-factor when it comes to winning and campaigning at the next GE, but the cold hard reality is that Boris has lost his USP and any winning pzazz has long since deserted him. He bumbled around in Devon at some point during the campaign and most likely made matters worse for the hapless Tory candidate, before foxtrot oscar-ing to Kiev and then Kigali.
He's a busted flush, but I don't expect the cult of Boris and the stiff-upper-lippers in the Tory faithful to admit that just yet. That would require clarity of thought and abandoning the current tactic of obtuse obstinancy.
