You want to know who Obama’s running mate is going to be?

Campaigns can afford to print up multiple posters — Kerry did that last time, and had Kerry-Gephardt posters ready for their rally. They’ll register all the possible domain names, so that’s not really a clue.

What campaigns can’t do is re-paint their plane with new decals several times over. Which is how I figured out Edwards was the pick at 2 a.m. the night before the announcement.

So I would keep my eyes on Obama’s campaign plane, which is in Honolulu Airport, last we heard. Obama’s vacation would be the right time to put up decals saying Obama-Kaine or Obama-Bayh or whoever, and roll it out along with the new running mate.
