Margaret Thatcher had a great idea: allow council tenants to buy their house cheap and turn them into Tories.
I bet the vast majority of Tory voters have a house with little or no mortgage.
Those tenants children and grandchildren, however, usually can't afford to buy houses, or, often, to rent homes as good as the ones Thatchers generation sold off.
Unsurprisingly they are not Thatcherites.
