Maybe.
Every coin has two sides though. Another interpretation could be that despite Corbyn running the campaign of his life, and surprising everyone in doing so, and despite him bribing 50% of the young voters with promises of free tuition fees; despite him successfully using social media to great advantage and despite Theresa May proving to be absolutely abjectly awful, offering literally nothing positive whatsoever, and running THE WORST election campaign in history... A hard left Labour party *still* failed to win anything like as many seats as the Tories.
Boris, for all his many, many faults, is infinitely more popular than May. The party will NEVER run a campaign that bad. They have already started putting out campaigning messages and bribing voters with promises of more money. Cynical, perhaps. Probably. But money talks and people are shallow. Some will not be persuaded but others will.
And Corbyn's popularity is way down compared to where it was. People regard him as weak and opportunistic. And the anti-semitism dark cloud hangs over him and his party.
He's one hell of a mountain to climb from such a low base. Can he do it, i.e. is it possible? Yes. Is it likely? I don't think so.
