Given the level of harassment that financial supporters of California's anti-gay-marriage proposition were subjected to, this produces a bit of foreboding in me. Visualize mailings to Dem contributors telling them which of their neighbors, co-workers, or employees are "radical right-wing extremists"
Then again, any national campaign of harassment against conservative supporters would likely have intense blow-back, even if not directly tied to the Dems.
Only if reported in the media.
