What's Next for the Presidential Campaigns?

John McCain had a high bar to reach last night with his acceptance speech at the GOP convention in St Paul. Not only was he following Barack Obama's historical performance in front of 80,000 Democrats the week before, he was also following the highly effective speech delivered the night before by his running mate Sarah Palin. McCain brought the party faithful to their feet with a mixture of his emotional personal story and a rousing promise to do battle with the powers-that-be in Washington. But can he resurrect the maverick persona with a voting record that's supported the current administration? We look at what's next for the campaign. Can both candidates to be the agents of change the country needs? Will Palin lead the charge in a sequel to the culture wars of the past? Should Obama fight back or take the high road?
