The numbers don’t add up. Corbyn played a blinder in the last election and attempted to bribe everyone with freebies, May made every possible mistake and upset her natural supporters. Labour increased its popular vote by a massive 3.5M over the 2015 election, yet May also got an additional 2.5M and still had 1M over Corbyn. All the conservatives have to do is not hack off the electorate with a dopey manifesto again......
I don't see this at all mate, though I can imagine it will be the Conservative thinking (I think I said as much in 2017).
Hesaltine and Iain Dale both wrote very interesting articles after the last election. Dale's in particular was a very astute analysis (far beyond most of the right or indeed the left). The Conservatives face a severe crisis of demography. Without being crude their voters are dying off and they are doing a very poor job at replenishing them at the other end.
I saw some (conservative) guys cheering when the "youth quake theory" was disproved (albeit the criticism of it went too far, it did exist just not in the way it was reported) as a major problem for Labour. Maybe it is, but it presents far more alarming issues for the Conservatives. If it wasn't largely young people flocking to the polls then who was it making up those numbers? It was increasingly 30 and 40 somethings, often with families going to vote Labour and Corbyn's Labour (in many cases from Conservative). These are a lot more solid voters than teenagers and 20 somethings who's votes will be more flexible and in truth will face quite sharp changes in lifestyle over the next 10 years (they might "grow up" as it were) and have more option to change. The smarter conservative voices can see the issue and weren't cheering on the news to be fair.
The demography crisis was very similar to social democratic parties on the continent who have been wiped out over the last 10-15 years. I remember giving them a similar warning and often you would be met with the same sort of arrogant response, that it was about the specifics of one campaign and/or 1 election. Labour went in a radically different direction, so much so most of the leading apparatus of the party would align themselves more with the Tories than the current leadership. That's the level of transformation it has taken for them to shift that pattern.
The other issue the Tories have got is that the "right" vote went down for the first time in 20 years in 2017. What May did was consolidate the right vote. This was always the golden opportunity for the Tories, they knew that they could allay many of the longer term problems by getting a huge vote and crushing Labour. They would then have the space to shift their image. It was a very sensible strategy in truth, but they have missed that opportunity big time. UKIP voters are going back to Labour at the same peed as going back to Tories (some even Liberals/Greens) and they will again eat into the Tory vote.
In a longwinded way I would say that May and her pretty shoddy campaign are a symptom not the cause of the problem. I would also note that most Tories I spoke to in the election wouldn't here a single word against her campaign, when I was telling them it was actually quite poor, I remember being told it was "fake news" by me. I do find it amusing to hear them now trudging that out as the excuse without having the humility to accept they called it wrong then.
When the history books are written I think they will look back and wonder how they messed it up after 2015. They pushed out their only leader to win a majority in decades and the most competent politician they had (Osborne) to cave in to the small minded wing of their organisation. Both Cameron and Osborne ran rings around Labour on the subjects that mattered to people (it's the economy stupid). I'm not a Conservative and never would be, but I always respected the big vision people they had who wouldn't get bogged down in either abstraction or questions of purity. They took realistic decisions to try to help people get on. It's unfathomable to me they have moved from that formula. For the most part it's because the lunatics are running the asylum. Any leader post May will be a further step in the wrong direction and the longer term trends will continue to bite them.
