Given the powerful emotions and hot-button nature of the topic, I wondered how the presidential candidates were messaging today's sad anniversary on their home pages. Here's a selection:

Barack Obama

"Remember 9/11. Unite Again."

Hilary Clinton

"September 11, 2001. We will never forget".

John MCCain

[nothing]

Mitt Romney

From soldiers guarding our liberty on foreign shores to those of us living under the umbrella of the protection they provide, we are united in remembering loved ones lost on that day and in our determination to protect our homeland from future attacks."

Rudy Guiliani

"September 11, 2001. We will not forget. This massive attack was intended to break our spirit. It has not done that. It has made us stronger, more determined and more resolved.”

John Edwards

"9/11/2001. We remember..."

Fred Thompson
