Will Kerry's Strategy Trump Bush's?

So far I've noticed that the Kerry campaign has absorbed Edwards' strategy (from the Dem. primaries). It is a positive campaign, avoiding attacks and mentioning the opposition's name as little as possible. They are basically running on 'this is John Kerry, and this is why you should vote for him..'

Bush's campaign has been largely negative. Attack! Attack! Attack! I truly believe this strategery is based on the fact that Bush really has little or no accomplishments to run on.

What strategy will prevail? (That is, if Al-CIAda stays out of it.)
