Please change the title. "Tories have lost the vote of the young, old and in-between generations".
They seem to at the moment, in that there seems to be a consensus that were an election to be held tomorrow, the Tories would lose it.
Personally, I am in a mixed mind about what the situation is. On the one hand, all governments fall eventually. After a period in office, the electorate become tired and bored of the same old, same old and eventually when enough of them want a change, the government falls. It is possible that this Tory government has simply run its course and that's all there is to it.
On the other hand, what gives me some hope, is that the Tories ran the most dismal election campaign ever, and still won. OK, not the landslide projected, but winners nevertheless. With THE most useless Tory PM the country has ever seen at the helm. They won, despite not really dismantling Corbyn's lunatic ideas and showing how and why his plans are simply undeliverable. The Tories ran a shockingly bad campaign.
Crucially, and this is a really, really big point, they forgot that there needs to be a positive vision of the future that people can buy into. People of all ages and demographics. If you say to someone, look we've got this terrible deficit and we must do something about it, people will in the main accept it if there is a "so that we can in future do xyz and deliver abc". They forgot all about the last bit. There was no "hope", no future vision of wealth and prosperity for all.
They need to have a long hard think about what policies should they be putting in place specifically to appeal to young people. What messages should they be putting out, what vision should they be painting. In short, a compelling message of WHY young people in particular should vote Conservative. If they were to do that, then who knows what the result of the next election might be.
What concerns me, is that (a) the current PM is clearly a walking disaster and needs to be replaced as soon as possible, and yet there seems little appetite to do so, and no obvious suitable replacements. And related to that, (b) the entire cabinet is packed with useless, uninspiring - or positively repulsive - individuals who would arguable fair little better. What the party needs is a total reshuffle. Press the <reset> button, get rid of the PM, get rid of at least half the cabinet and bring some new, vibrant, bright faces in with new ideas and some energy to revitalise the party. I really do think they need that.
