There were four other times in U.S. history when opposing presidential candidates were from same state:

1860: Abraham Lincoln (Republican of IL) v. Stephen Douglas (Democrat of IL)

1904: Theodore Roosevelt (Republican of NY) v. Alton Parker (Democrat of NY)

1920: Warren Harding (Republican of OH) v. James Cox (Democrat of OH)

1944: Franklin Roosevelt (Democrat of NY) v. Thomas Dewey (Republican of NY)

And of course, the most current election will have:

2016: Hillary Clinton (Democrat of NY) v. Donald Trump (Republican of NY)

FYI, Amendment XII of US Constitution requires President and Vice President to be from different states.
