First radio report I've heard (CBS Radio news) played a complete clip of Kerry's speech (yes, Kerry, not Cheny), then went on to say that Cheny went on the attack. They played this clip from Cheney's speech, one sentence .. "And the Senator from Massachusetts has given us ample doubts about his judgment and the attitude he brings to bear on vital issues of national security."
The Kerry stuff they played included mention of Bush landing on a carrier (Kerry talking), and that the effort in Iraq is not yet wound-down, etc. That is, the clips selected for Kerry included SPECIFIC comments, the clip of Cheney did not.
