In response to Obama's comments about terrorism, Rudy Giuliani knocked Obama earlier today:

Throughout this campaign, I have been very concerned that the Democrats want to take a step back to the failed policies that treated terrorism solely as a law enforcement matter rather than a clear and present danger. Barack Obama appears to believe that terrorists should be treated like criminals -- a belief that underscores his fundamental lack of judgment regarding our national security. In a post 9/11 world, we need to remain on offense against the terrorist threat which seeks to destroy our very way of life. We need a leader like John McCain who has the experience and judgment necessary to protect the American people.

In addition to the conference call Kyle reported below, Obama himself responded to the McCain campaign's attacks:

"Let's think about this: these are the same guys who helped engineer the distraction of the war in Iraq at a time when we could have pinned down the people who actually committed 9-11," Obama told reporters on his campaign plane. He said his statements about Guantanamo were intended to suggest that suspects have a right to be heard, not freed, and accused McCain of playing political games on national security.

"What they're trying to do us what they've done every election cycle, which is to use terrorism as a club to make the American people afraid," Obama said.

Reminded that the Republican playbook worked in the 2004 presidential race, Obama countered: "Well, it's 2008."

"I'm looking forward to having a robust argument about this issue," he said. "I don't shy away from it. The way these issues have been framed have done a great disservice to America. They have not made us safer."
