Penny --

You're right on the goose! On the ninety-six candidates, contributing states were:

1) New York (25)
2) Illinois (10)
3) Indiana (10)
4) Ohio (10)
5) Massachusetts (5)

Sixty of ninety-six candidates. At least one candidate (and sometimes two or three) from these five states ran in every one of these elections.

Of course this isn't counting candidates from other Northern states such as Pennsylvania and New Jersey.

Boys and girls, can you say "domination"?

Excepting Francis P. Blair of Missouri who ran as an unsuccessful Democratic candidate for VP in 1868, the first Southerner to be nominated for president or vice-president in the postwar era was Joseph T. Robinson of Arkansas in 1928.
