1860年アメリカ合衆国大統領選挙
Eventually, the state party worked out an agreement: if either candidate could win the national election with Pennsylvania's electoral vote, then all her electoral votes would go to that candidate. Of the 27 electoral candidates, 15 were Breckinridge supporters; the remaining 12 were for Douglas. This was often referred to as the Reading electoral slate, because it was in that city that the state party chose it.
↑ The Douglas ticket in Rhode Island was supported by Breckinridge and Bell supporters.
