(CNN) - Another question, another laugh line from Sen. Joe Biden, D-Delaware.
When asked by moderator Wolf Blitzer whether he would support the Democratic nominee "no matter who that nominee is, no ifs, ands or buts," Biden jokingly replied, "Hell, no. I wouldn't support any of these guys."
When the laughter died down, he said he would indeed support them all. The other candidates unequivocally answered in the affirmative, except for Ohio Congressman Dennis Kucinich, who said, "Only if they oppose war as an instrument of policy."
