A new approach to politics?

My take on one theme in Cameron's hour long speech to the Tory conference:

Political apathy, Mr Cameron observes, is rife amongst British voters. A prominent cause of this, he continues, is the dismal level of public respect for politicians. Politics is seen as a dirty business, populated with career-focused individuals continually making empty promises, orating vacuous principles and introducing pointless schemes that are more gimmick than policy.
But wait, vote Conservative, and you can banish all that to the past! Such maladies are ‘old politics’, belonging to the realm of Gordon Brown and (not so) New Labour. Here in Bournemouth, things are different.
For a start, there is the charming friendship of David Cameron and William Hague. As Cameron lovingly states, ‘some people say that there is no such thing as friendship in politics but I can tell you… that there is no better friend.. than William Hague’ (camera focuses on Hague, who looks genuinely delighted).
Throughout course of his speech, Cameron made a whole raft of pledges about the new type of political practice that he and the party would be undertaking. Most important is this: the Conservatives will be staying true to their traditional values and they will be applying these values to the central problems facing modern Britain, adapting their methods to the rapidly changing technological context.
More specifically, Tory promises will be sincere, and they policy effective. Their motivations will be transparent and it will not include pandering to the whims of swing voters.
The days of party-political bickering (at least from the Conservative side) will be over. Where Cameron criticises Labour in his speech, he makes a point of doing so for a specific reason: ‘If we don’t understand why Labour are failing we won’t succeed ourselves’. Labour, in the world depicted, are decent guys trying to do good things but failing because of policy areas (and thus, implicitly, incompetence).
From one angle, this approach is exciting. Cameron is pledging to revamp politics into something new, fresh and meaningful. He gives us an inspiring vision of the politician. We must no longer see the men in suits as dishonest and sleazy but as noble individuals dedicated to public service. As his speech draws to a close, he rallies his party with these words ‘And do you know the greatest service that this party can do to our public today, it is to get out and fight for what we believe in and the changes we want to make’.
The dream is not without appeal, but scepticism will have the last paragraph here. For in declaring his allegiance to a new politics, Cameron runs the risk of being a paradigm example of the old. If the Tory approach lacks the virtues Cameron promises, then those promises will have been broken. Worse still, they will look like a cynical attempt to woo the swing voter.
