Just would like to know if this $51 million came from large numbers of small contributions? Or has there been a transition toward corporate (corporate-managed personal) large contributions? So I guess I would like to know how many contributors and the average size of contribution, relative to, for example, last February and March?

Are there any published answers to these questions? If so, where? Obviously I am concerned about the direction of the Obama campaign, and the well-worn phrase "follow-the-money" applies here.
