I can only go by 1960 onwards so here it goes:
Top Ten Worst:
1. Thomas Eagleton
2. Sarah Palin
3. Curtis Lemay
4. Dan Quayle
5. Spiro Agnew
6. Geraldine Ferraro
7. Joe Liebermann
8. James Stockdale
9. Bob Dole (for his "Democrat Wars" comment)
10. Tim Kaine (he didn't really hurt the ticket, but he didn't help either and made a buffoon of himself in the debate with Pence. He also reinforced the notion that Clinton was too establishment)
Top Ten Best:
1. Walter Mondale
2. LBJ
3. Al Gore
4. George HW Bush
5. Joe Biden
6. Mike Pence (as someone else said, he gave Trump the Evangelical Vote. Another VP might've lost Trump the election)
7. Dick Cheney (for all the man's evil deeds and faults, he did help Bush in 2000 and it was seen as a respectable choice on both sides of the isle at the time)
8. Hubert Humphrey
9. Edmund Muskie
10. Jack Kemp
Nice to see you did not include William E. Miller on the "worst" list.
Goldwater was doomed to defeat no matter what and Miller really didn't do anything to hurt the ticket. The others mentioned in my "worst" list did.
