Who: The Obama/Biden campaign
Where: A web ad
What's going on: The Obama campaign is attacking Mitt Romney in an ad that features "man-on-the-street" interviews that ask the question: "Do you have an offshore bank account?" The ad flows from a Vanity Fair report that investigated Romney's finances and where he keeps some of his millions.
The punchline for this ad is supplied by one man who says: “I don’t have an overseas bank account, and I don’t think our next president should have one either.”
As I said earlier in the day, this issue may be a very big problem for Romney.
