Defeat for Kerry is certain but the divide remains. Here's what Bush could do to really lead:
1. Admit his mistakes. Claim the errors in Iraq. He can now credibly claim that this is America's war, not just Bush's war. He must make efforts for everyone to feel committed to it's success. The left won't feel as much partisan satisfaction by hearing about Iraq failures as it did. This is an opportunity to unite.
2. Appoint a democrat to cabinet. Or even a Hagel or McCain. "If you're unsatisfied with how things are going, help fix them." For a second Bush term to be successful, he needs to start leading the entire nation, not just his extremist base.
Will he do this? I seriously doubt it. Slash and burn partisanship has served him well. Why change success strategies. The only hope is that the reality of his failed policies will force him to embrace the left for the sake of his legacy.
