Strained Presidential Tickets?

[Lincoln Republican]

Can you name some Presidential tickets in which the Presidential candidate and the Vice Presidential candidate, on the same ticket, did not get along  well, or possibly didn't like each other?   

Who are they, and in what Presidential election year did they run?

Do you know of any specific problems this ticket may have had with one another?

[Lincoln Republican]

Lincoln and Johnson in 1864 is the pretty obvious answer.  They were in different parties and probably agreed on little.

I'd also say JFK and LBJ in 1960.  It ended in LBJ murdering JFK, 42 years ago today, so I can't see them as the best of friends.

Whoa!  That's a pretty strong accusation about LBJ murdering JFK.

This being the 42nd anniversary to the day though of the JFK assassination is somewhat strange, however, I must say.  I wasn't thinking of that, though, when I posted this question.
