Cameron's Speech: National Interest vs Self Interest

This is what stood out for me in Cameron's speech to the Conservative Conference today.  He was clear that his party is acting in the national interest, as is Nick Clegg's, and in his call to the public to join in the work - to volunteer, set up a business, engage with their public services etc.  Together in the National Interest - the words were said so many times it was almost too much, but that is how to get a message across (we can all learn from Brown on that point).

Of course the unsaid comparison is with the Labour party - the party of vested interests (the unions) that acted against the national interest (the large public debt the country now has) and even, in Ed Miliband, perhaps a selfish leader?  A man who sacrificed his brother for his own ambition and who is 'too busy' to put his name on his child's birth certificate?

A clear message then, but are the voters listening?  I can't wait for the next polls to come out.
