Lesson of the day: John McCain doesn't much like to see his bravery challenged.
After the last debate, Barack Obama said he found it odd that McCain hadn't brought up former Weather Underground member Bill Ayers, considering that the McCain camp's Ayers offensive had then just begun.
"I am surprised that, you know, we've been seeing some pretty over-the-top attacks coming out of the McCain campaign over the last several days that he wasn't willing to say it to my face. But I guess we've got one last debate. So presumably, if he ends up feeling that he needs to, he will raise it during the debate," Obama told ABC News' Charlie Gibson.
