Yesterday doing my research into candidate Christine O'Donnell to see if the slander and the dirtypolitricks.com thats been lobbied against her has any teeth (and it doesn't from what I can see thus far)
I noticed this ->
Notice when you type in "Christine O'Donnell" into search query, not a mention of her candicy. You would have to type in "Christine O'Donnell for Senate" to see the sponsored link.
Not the case for her Opponnet Chris Coons where as only his name would be surfice.
