By many accounts, President Bsuh was more effective on Friday night when the questions turned to domestic affairs. Similarly, during Kerry's senate career, he has demonstrated more passion for foreign affairs issues than for domestic affairs. Finally, any opportunity for Bush NOT to talk about Iraq, is a boost for him.
Given the CW, that his adjustment in Debate 2 seemed to solve his problem with Kerry, I would expect expectations to be that this will favor Bush's bullet point approach. By contrast, the danger for Kerry is that he gets bogged down in wonkish talk, long-windedness and name dropping. Finally, Bush is still ahead by a point or two in the poll averages. So all in all, I'd say Bush has the edge going into debate 3.
