Not so long ago, the main interest of the Tory Party was winning elections. And they were rather good at it, so that of the first 50 years of my life, 39 were lived under Conservative governments. Their next (and closely related) big interest was running the economy efficiently.
In that Tory party, Theresa May, who called a completely unnecessary election and threw away a parliamentary majority, would not have lasted five minutes. But the modern Tory party seems quite uninterested in the economy or winning elections. Indeed, the only Conservative leader who has won one in the last 25 years was dumped barely a year later.
So in this new Tory party, expect to see Theresa May stay on for at least another couple of years. She has a crucial job – scapegoat. The vast majority of Tory MPs (including, I suspect, a number of those shouting loudly for Brexit) know that leaving the EU will be a disaster. So it is vital that May stays in office until Brexit is completed and all doubt about its disastrous consequences dispelled. Then she can be blamed for the disaster and cast aside, so that a new leader can fight the next general election.
But there is another reason why May is likely to stay. At the moment, It would be hard to prevent any Tory leadership election from turning into open war between supporters of moderate and extreme Brexit. But once we have left the EU, the question of how damaging a Brexit we choose will have been resolved, and with a bit of luck there will seem to be no point re-fighting old battles.
Whether any of this will save the Tories is another matter. With Labour finally threatening to show some common sense, Brexit is likely to be seen increasingly as a Conservative project. And the unprecedented incompetence with which it is being executed could do permanent damage to the Tory brand.
