Today's installment of campaign-related news items that won't necessarily generate a post of their own, but may be of interest to political observers:
* The Obama campaign released its closing negative ad over the weekend, hitting Mitt Romney on taxes, Medicare, and Wall Street. It will air in swing states.

* In New Hampshire, PPP found Obama leading Romney by only two, 49% to 47%.
