This is a homeland security, national security issue and I think Republicans think they own this issue and they don't want to give Democrats an opening.

I thought it was a strong night for the Republicans, John McCain talking about national security defense and foreign terrorism. I think Rudy Giuliani did a pretty good job of mixing criticism of John Kerry -- and talking about the president and his efforts on the war on terror. It was a good start. The only question is: How does it build? And will Vice President Cheney and President Bush close the deal?

It once again positions Republicans as the stronger party on national security and defense. It's persevere and win versus cut and run.

I think you're going to see a heavy concentration in the months ahead on national security items and making sure that terrorism doesn't revisit American shores.

The Xerox machine is one of the biggest threats to national security ever devised.

AIDS and malaria and TB are national security issues. A worldwide program to get a start on dealing with these issues would cost about $25 billion... It's, what, a few months in Iraq.
