The modern laws of media hype and political warfare have a useful tenet: Repeat ANYTHING or raise false concern over ANYTHING and it is likely to be planted in the conscious/subconscious of many voters.

GET WITH THE PROGRAM PEOPLE. The "rising above it" bullshit has served us so well in the past, hasn't it?
If you have problems with the story, then STFU and get out of the way of Dems who are engaged in MODERN POLITICAL WARFARE. Go tend your garden or some other pedestrian task, because the "concern trolls" are not helping shape the message.
