@Foxfyre,
Anybody, with enough time and some resources to waste, can sue anybody for anything. Remember the suit to abolish the findings of the 9/11 commission?
If you dont accept the basic information, then so be it.
I can see that the Obama cam,paign doesnt want to ower itself by responding to the "lawsuits", for to do so may require that funds be expended, and just to present the same information via the normal channels should keep them oiut of the suit (has anyone even been served?).
