But you can call them Barack, Michelle, Malia, & Sasha.

"But what was Palin's code name? I'm hoping for "Moosebane.""

This article at the Chicago Tribune sez, "Denali."

Interestingly, while that article mentions the Obamas' names are alliterative, it appears every family has been since JFK:

Tumbler/Tempo
Eagle/Evergreen/Energy
Timberwolf/Tranquility
Rawhide/Rainbow
Deacon/Dancer/Dynamo
Passkey/Pinafore
Searchlight/Starlight
Volunteer/Victoria/Velvet/Venus
Lancer/Lace/Lyric/Lark

It's almost as much fun as the names for Japanese Imperial reigns. (Meiji, Taishō, Shōwa, Heisei)
