Perhaps "immovable" is not the right word there, at least to describe the Labour vote at the last election. The vote that Corbyn got out voted for mostly rational reasons based on politics that is simple to understand - they had issues (lack of housing, lack of quality jobs, attacks on pay and conditions, student debt etc etc) that where becoming / had become serious issues for them, Corbyn proposed to deal with them and they believed him. Given that no likely alternative Labour figure, and certainly no Lib Dem / Tory, is going to do what Corbyn did you're right to say that they are probably going to stay with him - but they are going to stay with him for reasons that can easily be understood.
The Tory vote however does genuinely look immovable - despite almost nightly evidence that they are dangerously incompetent at best, the vote stays with them and it seems to be staying with them because of the notion they have of what Corbyn is. Without challenging that notion effectively it will be very difficult, if not impossible, to win.
That vote was in the teeth of sustained and unrelenting sabotage from within his own ranks . With many who were standing for election even telling voters they'd no chance of winning because of who their leader was .
That massive treachery definitely cost them a lot of votes , it was bound to . The result has made it much easier for him to stamp his authority internally . The chief fifth columnist charge against him was that he was unelectable . Clearly that's no longer the case . So logically a more united party with a leader many now see as future pm material rather than a radical fringe laughing stock would stand a much better chance in another electoral contest .
Similarly the post election Tory meltdown and series of humiliations , the DUP deal etc has impacted very negatively on the Tory image . They did badly when they looked unassailable and now look even worse post election . They can definitely lose votes in that scenario .
The election result itself has challenged the notions and conventional wisdoms . The ground has shifted politically . Central to that has been the myth of Corbyn and his policies being electorally toxic , out there, weird , fairytale stuff assuring a landslide to his opponents. No longer the case . That will make more people think about just how wise the wisdoms and their purveyors are . Look at stuff differently, believe change is possible . Add to that a much more assured and confident Corbin who's definitely growing into his role the longer he's in it and it may well be possible to turn people around .
