Snap poll showed 48% for Corbyn, 52% for Johnson. Now that sounds like a win for Johnson, but generally speaking if a leader outperforms their parties share of the vote then that means they probably won some people over and they get a boost in the polls.
Not that I thought Corbyn was especially fantastic, but he didn't have to be in order to outperform expectations. The problem for the tory newspapers is that they demonized him so badly he just has to turn up and not have two heads and he goes up in the polls.

Yes that is correct, but it is factored into the polls. However, will the elderly turn out in Winter? A small but significant % will be too sick to go to the polling station.
Additionally kids traditionally don't vote but more seem to have registered this time.
Difficult to say what will actually happen but it isn't that hard to make a case for unknown variables giving Labour a boost over and above the polls.

There is a huge difference between unlikely and possible.
