One of the things that I think you see sometimes in politics is a certain degree of caution. It's usually advised by consultants who don't want to see you march to the end of a limb.

We discussed politics, but we also talked about the importance of hard work, personal responsibility, living within your means, keeping your word. Those lessons stay with you throughout your life.

The world of politics is always twenty years behind the world of thought.

I think that politics could be a positive thing. My beef is that people focus on the personal aspect of a politician too much. They should focus on the results.

No science is immune to the infection of politics and the corruption of power.
