When people tap into this politics of resentment, it usually ends ugly.

We cannot hope to change human nature. There will always be cranks and conspiracy theorists among us.

I'm an independent. I'm a centrist. A new generation is arriving that has grown up with a multiplicity of choice in every aspect of their lives, and yet politics is the last place that they are told that they should be satisfied with a choice between brand A and brand B.
