Isn't Kerry intimately affiliated with the DNC, as though they were his employers? I'm not convinced they dont have standing to represent Kerry.
If he is, then both Kerry and the DNC are in violation of the Federal Elections rules. Kerry as a person and as a candidate MUST be separate from the DNC. Indeed the Kerry Edwards campaign must be separate from the DNC. The DNC can support Kerry, but they cannot act on his behalf in a personal matter. That would be improper.
Here you have a lawyer for an organization that by law must be independent of the candidate threatening lawsuits on the candidate's PERSONAL behalf in order to frighten media outlets into squelching a advertisement.
If the republicans tried this, all hell would break loose. Since it is the democrats doing it, they will get the media's support.
