From NBC's Mark Murray and Chuck Todd
Contrast these two reactions today to Bin Laden's videotape...
McCain, per a statement: "The release of the purported bin Laden video starkly reminds us that there is no greater responsibility for a president than to protect America from attack and to command our military forces in a time of war against a barbaric enemy -- an enemy plotting every day to kill Americans. Osama bin Laden and his henchmen must be hunted down -- and as president, I will... My presidency will be al Qaeda's worst nightmare."
And Thompson, per the AP: "Bin Laden is more symbolism than anything else," he said. "I think it demonstrates to people once again that we're in a global war."
