Here's a list from one of my derailed threads, MLK doesn't die:
1968: Fmr. VP. Richard Nixon R-CA/Gov. Spiro Agnew R-MD
1972: Pres. Richard Nixon/Sen Bob Dole R-KS (Agnew resigned due to guilty conscience)
1974: VP Bob Dole/Vacant
1976: Sen. Martin Luther King (Jr.) I-GA/Gov. Ronald Reagan R-CA
1980: Pres. Martin Luther King (Jr.)/VP Ronald Reagan
1984: Gov. Gerry Brown D-CA/Sen. Paul Tsongas D-MA
1988: Pres. Gerry Brown/VP Paul Tsongas
1992: Sen. John Danforth R-MO/Businessman Ross Perot I-TX
1996: Pres. John Danforth/VP Ross Perot
2000: Gov. Jesse Ventura Ref-MN/Rep. Ronald "Ron" Paul Ref-TX
2001: VP Ronald "Ron" Paul/Vacant
2004: Pres Ronald "Ron" Paul/Gov. Charles "Charlie" Rodger Jacobson R/I-MI
(He was going to be my second "main character" in my timeline, he's the fictional Governor of Michigan from 1999-2011, and from the fictional town/city of Mackinack. Its located where the Mackinac Bridge and Mackinac City is.)
2008: Sen Hillary Clinton D-NY/Gov. Brian Schweitzer D-MT
2012: Pres Hillary Clinton/VP Brian Schweitzer
2016: VP Brian Schweitzer/Gov. Barack Obama D-IL
2020: Sen. Charlie Rodger Jacobson R-MI/Gov. Nikki Haley R-SC
2024: Pres Charlie Rodger Jacobson/VP Nikki Haley
2028: VP Nikki Haley/Gov. George (P.) Bush R-TX
And that's where the timeline would end.
Why would MLK Jr. and Ronald Reagan run on the same ticket? King would have been disgusted by everything Reagan stood for.
