No Serious Threat To Cameron

We know the grumbles , Ealing , Grammars and now the Rawanda vac .So does any of this amount to a serious threat to Mr Cameron's leadership?
For a number of reasons, no despite The warning, or threat, coming from top Tory donor Lord Kalms. He has turned up the pressure by clarifying his message to the party leader as "look chum, you need to do some re-thinking". , but remains supportive. There us no threat for the following reasons

Firstly, the rumblings against him are indeed mostly confined to that small group of "traditionalists" who have never supported him .Mr Hague is reassuring right-wing on Europe .Secondly, most in the Tory ranks in Westminster appear to have had enough of routinely dumping their leaders . There remains a desire, just as there was with Labour and Tony Blair in the mid-1990s, to unite behind a man they see as a potential winner, despite some misgivings . And, while Mr Brown's early success has seemed to force the Tories onto the back foot, party bosses are reminding any jittery MPs that it was only to be expected .
Then there is the question of "if not Cameron, then who"? Frontbenchers including Liam Fox and William Hague are currently out and about making speeches on issues like Europe designed to reassure those on the right of the party. But no one believes any of the right-wing candidates would currently stand a chance of replacing Mr Cameron, or are even planning to do so. David Cameron is secure and suggestions otherwise are rubbish
