Wow. Here's hoping that we don't lose everyone up to Thomas Vilsack. If history is any indication, the line would only go as far as vice-president.
These nine vice presidents have taken over for their bosses due to death or resignation. The line of succession has never gone further than vice president.
1. John Tyler (1841) (William Henry Harrison died after 30 days)
2. Millard Fillmore (1850) (Zachery Taylor kicked the bucket)
3. Andrew Johnson (1865) (Lincoln assassinated by a coward)
4. Chester A. Arthur (1881) (Garfield killed by doctors more than his assassin)
5. Theodore Roosevelt (1901) (McKinley assassinated)
6. Calvin Coolidge (1923) (Harding bought the farm)
7. Harry S. Truman (1945) (FDR had an aneurism)
8. Lyndon B. Johnson (1963) (Kennedy assassinated by hillbilly)
9. Gerald Ford (1974) (Nixon resigned)
