Vice presidents

I started this thread so I could ask all of you,who you thought would be Ron Paul's VP.
I personaly cant figure it out.
Who are his options?
And I dont mean some out of left field choice,just the most logical.
Thanks for adding to this ahead of time.
Also I want this thread to be about all the canidates potential vps.
So feel free to try and figure out the possibilities for Hillary and Obama as well.And anyone else would feel like working on.
