Philadelphia (CNN) - It's a large district in and around Philadelphia. It's not a swing seat; it's a safe Democratic stronghold-not a nailbiter. But in this midterm election, the 13th Congressional District race has attracted some national attention and some rock star fundraisers: Bill and Hillary Clinton.
Why such attention and star power? Because the candidate is Marjorie Margolies: related by marriage to the Clintons and tied to the former President by history.
