Nadine Dorries, on the Today programme this morning, suggested that the time limit for abortion would come down if the Tories won the next General Election.
The American Republican Party has been keeping itself in existence like that for forty years: promising to ban or at least restrict abortion, but never doing the slightest thing about it, because those on whose votes it has come to depend would then declare "Mission Accomplished" and go home to the Democratic Party, whence they came and where their economic interest actually lies.
But the Tories could never pull off that trick here. Just as by far the most socialised sector would still never vote Labour in a million years, so the Catholics and the black-majority churches would never vote Tory in a million years. That's just the way it is.
Instead, common cause begins elsewhere.
