USSS Code Names: Biden and Palin

Biden's is "Celtic."  His USSS detail doesn't seem to be certain if it's "Celtic" as in the basketball team or "Celtic" with a hard K.

And the Palin family has chosen the letter D:  Denali for her, Driller for him, according to Anne Kornblut.

Outing these code names doesn't harm anyone, no worries, although the campaigns, having had the Secret Service emphasize operational security procedures to them ad nauseum, have asked staff members not to talk about these things.
