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:

* In South Carolina, Elizabeth Colbert Busch is the first Democrat to go on the air in the upcoming congressional special election in the state's 1st congressional district. The spot does not mention her party affiliation.
* In Michigan, latest survey from Public Policy Polling shows Gov. Rick Snyder (R) struggling badly with a 37% approval rating. What's more, Snyder trailed Democrats in hypothetical match-ups, with Rep. Gary Peters (D) leading the incumbent by seven, 44% to 37%.
* Jim Messina, President Obama's former campaign manager and now the head of Organizing for Action, announced this morning that the group will not accept corporate donations, and vowed to be "open and transparent" about the group's fundraising.
