Max Hastings is on point:

Much of successful political leadership, like all human relations, is about making people feel good. This was an art in which Mr Blair excelled, his path smoothed by a benign economic environment and an unfailing readiness to reject tough choices in domestic policy. 

Mr Cameron will have no hiding place. He must tell the British people that in 2009 their long weekend ended; that if the nation is to regain prosperity in the third decade of this century, during the second it must change its ways and pay awesome bills. On Mr Cameron’s watch, economic bombs will start exploding. To persuade the country that these are not his fault, but the result of past follies and delusions that are no longer affordable, will require the skills not merely of a good politician, but a great one. 

Barack Obama can tell him all about it.
