Theo,
You're right about the real old days. Whowever came in second in the popular vote automatically became vice-president, and rightfully so in my book. Let's say 51% voted for the current President/49% for the vice-President of another party, we all know that the runnerup has no influence in the winner's approach to the job. If the main man dies, who better than the 49% representative take over the job?!
