The average American voter seems to value style over substance (see "Clinton, B.J."), so in that I can see validity to D'Amato's statements. While Cheney is 100 times the man Edwards is, and will likely dismantle Edwards in a debate, I don't think Joe Voter will see that. However if Bush were going to replace Cheney he should've done it months ago. If he did it now the headlines would read: "Panicky Bush Dumps Cheney", subhead: "Questions Over Haliburton Too Damaging".
What questions over Haliburton?
