There are basically three questions:
1. Why is Obama hitting PA?
2. Why is McCain hitting Iowa?
3. Why hasn't Obama released his September fund raising?
1) To drive up turnout and shore up the state so he doesn't have to visit the last two weeks before the election.
2) Because he's trying to win the election and he doesn't have many other options.
3) Why would Obama release his September fundraising now? Releasing it now would just help the McCain campaign, by letting them know what resources Obama has left. The smart thing is to wait until the last day required.
