Let’s face it they need the people they call scum to vote for them next time if they want to win.
Nah, the tories are doing such a grand job of killing or scaring off their key demographic that they're not going to win the next election (not that they want to anyway).
Who votes for the tories?
The old, the rich and the better off. The old are dying quicker now thanks to tory austerity, the rich are being scared off because tory ineptitude has curtailed investment opportunities and trashed the economy, the better off are reconsidering because they're being financially impacted by tory mismanagement.
The next year or so will see Rishi's crew of theives asset strip as many public services as possible, while setting fire to the shells that are left behind, before they're kicked out in 24.
The tories have no interest in winning the next election because they know they've fucked up so badly it will be impossible to fix. Better to let Labour take the helm for a few years, let them put out as many fires as they can, while the tories snipe from the sides.
Then once things have been settled and rebuilt the next generation of tories can come back in and repeat the process. So it was, so it is, so it will be.
