Some may belittle politics, but we know - who are engaged in it - that it is where people stand tall. And, although I know it has its many harsh contentions, it is still the arena that sets the heart beating a little faster.

The rule of law not the rule of the secret police. The spread of freedom is the best security for the free. It is our last line of defence and our first line of attack.
