Bobby Kennedy is not assassianated at the hotel. He wins the nomination barely on the first ballot at the DNC over Humphrey and McCarthy. Kennedy thanks his supporters and selects George Smathers as his running mate.
On the republican side, the stop Nixon movement works and there is no nominee on the first ballot in a race between Nixon, Rockefeller, and Reagan. Rockefeller prevails on the second ballot and he selects Ronald Reagan as his running mate.
George Wallace runs as an independent and he selects Curtis LeMay as his running mate.
Kennedy/Smathers: 249 Electoral Votes
Rockefeller/Reagan: 251 Electoral Votes
Wallace/LeMay: 38 Electoral Votes
You will be wondering about the big three in the north (Illinois, Indiana, and Ohio.) Illinois and Ohio were close in 1968. Wallace swings those to Kennedy. The people in Indiana will remember being comforted by Bobby when Martin Luther King Jr. was killed. Remember he announced King's death at a rally in Indianapolis. Missouri was close also in 1968 and Wallace helps Kennedy there.
The election goes to the house and Kennedy is elected President.
