We've had elections where a previous President faced off his successor, one with three Presidents past, present, and future, an election with two Vice-Presidents, even one with two Speakers. For the purposes of this challenge, I'm not counting it when former/present Secretaries went against future men: 1824, 1836 (with Webster as the Massachusett's Whig nominee), and 1848.
How can we get two Secretaries of State (either both previous or one incumbent) as their Parties nominee's?
