How long can Kerry / Edwards continue to run positive campaign?

[kentuck]

Kerry has thus far stayed out of the mud with the Republicans. Most of his ads have been positive and self-defining. And he has come from behind to running rather comfortably in the lead at the moment. All this advantage coming despite $80 million dollars worth of ads spent by Bush/Cheney - most of it on negative ads? What can we glean from this, if anything?

But the Republicans have put their attack machine into high gear with the choice of John Edwards as VP. Will Kerry be able to still maintain his lead in the polls? If so, should he continue to run a positive and optimistic campaign and leave the Repubs wallowing in the mud alone?

1. He should remain positive

and focus on the good that he and Edwards can do. Let the Chimp mobile continue to run the silly negative stuff and pretty soon people just might get really tired of it as they are with all the other lies we've been told.
