Why settle for being second fiddle when you can strive to be first?
I don't think that being vice president is all that bad though. Maybe a little bit on the boring side since you wouldn't have a lot of constitutional obligations to fulfill, but still, you're the first person in line for succession to the presidency should something happen to the current president. Also, if you want to run for president yourself when election time rolls around, I'm sure it looks pretty dang good to people that you once held such a high position in government.
