Jack,
      Lieberman is NOT a very wealthy man. With the high cost of fuel today airline prices are very expensive. If he has to pay out of pocket to travel all around the USA, he has to be getting something in return for it. I am sure he is not going by Greyhound. On the other hand, if the McCain campaign fund is paying the expenses they must consider Lieberman a very special person who is important to their efforts; important enough to be VP.

Would I do it? Only if someone paid my Amtrak fare. I don't fly.
