McCain: it is much less than 7 years ago. holds up his record in supporting changes that have been made to protect against that type of tragedy.

Obama: we are safer in some ways but not in other. need to do more on chemical sites, transit, and ports. Spending on missle defense, but we need to spend more on anti nuke proliferation. and finally we must restore the perception of US abroad.

Both candidates condemn torture.

McCain is making a strong case about the danger of defeat in Iraq and trying to paint Obama's positions as essentially equal to defeat.

Obama brings up the threat that China poses since we are distracted by Iraq and cannot compete with them for influence. Claims that economic decline equals security decline. blames all this on Bush's lack of a broad concept of security.

McCain: does not believe that Obama has the experience or judgement to be president. condemns Bush's stubborness in Iraq, which gets a laugh from Obama!

Obama is addressing the camera and he is now making the emotional appeal to the voter about our loss of standing in the esteem of the world.

McCain continues to address Lehrer, but he finishes by bring back up his war hero image.
