I think by not participating in the current political debate, hopefully I'm sending a signal that will help set a tone.

Life in America shows that liberty, paired with law, is not to be feared.

The terrorists are fighting freedom with all their cunning and cruelty because freedom is their greatest fear - and they should be afraid, because freedom is on the march.

Oftentimes people ask me, 'Why is it that you're so focused on helping the hungry and diseased in strange parts of the world?'

Other Republican candidates may retort to personal attacks and negative ads.

Thousands of trained killers are plotting to attack us, and this terrible knowledge requires us to act differently.

I'm the only president who really put it out in the State of the Union and was very specific about how I felt we ought to do it.
