All kidding aside, I'm curious...do you think he uses fingerprint scanners? Are there full time staff at each house, so it's not a concern?
But more to the point...let's keep playing this up.
I suggest keychains be handed out to everyone at the Democratic Convention. Maybe we can put a checklist on the fob, so that we can all keep track of all the houses we have (What, you've never lost count of your houses before?). Can't you see everyone jingling their keys in unison (or key, as the case may be)?
Of course, you couldn't fit all of his keys on one keychain anyway. He probably has an assistant delegated with key management.
But I digress, the question is: How can we make this happen, and who's down to help?
Let me know in the comments, and I'll start working on any actionable advice I get.
UPDATE: This guy has the idea:
I also took my first shot at a keychain here:

If you're interested in pooling resources and sending some of these to Denver, or if you're down to distribute them in Denver. Let me know.
