[Hieronymus]

Where did you learn your history? In the 20th century alone, teddy R., Coolidge, Truman and LBJ all became president upon death, and each went on to be elected for a term. Ford should count for something, and Nixom as well. People who first served as veep have been president less than half but more than 40 percent of the 20th century.

[Theodore R.]

I think he meant elected as the sitting VP.
