Actually William R. King had a terminal illness and would have died within a month after taking office...assuming he would even have accepted the office (he was in Cuba at the time Taylor died, for health reasons).
The new President would have been DAVID RICE ATCHISON. Which, if you have ever read anything about him, was VERY SCARY to contemplate as POTUS.
? From what I can determine, King's health didn't fail until 1852. He was in Washington in 1850 and was still well enough to serve.
If Taylor dies with no VP, there will have to be a special Presidential election that fall; so King or Atchinson would only serve until January 1851.
True but if they both die (taylor and fillmore) than there is trouble. Besides it usually only takes one shot
