Republican Christine O’Donnell claims to have raised $2.6 million in her longshot race to represent Delaware in the U.S. Senate. The DSCC evidently believes that she must be taken seriously. They’ve just purchased another $165,000 in airtime against her, according to FEC reports, bringing their total so far to $272,000.

So if you count Delaware, Pennsylvania ($3M), and Missouri ($1.5M), the DSCC has split about two-thirds of its expenditures so far between races it probably cannot win and races it supposedly cannot lose.
