POD 1: George Wallace chooses Albert "Happy" Chandler (former two-time Kentucky Governor, Senator and Commissioner of Major League Baseball), as running mate and tells those Electors who object to his choice of the former Baseball Commissioner who allowed Jackie Robinson into the major league to "go to Hell!" (IOTL as he felt he should have after the election). Wallace no longer has a his IOTL 'use-the-a-bomb' problem with running mate Curtis LeMay - which became a scare factor driving away some voters from his ticket. In a number of close states this works to Wallace's advantage and Nixon's disadvantage (and would reflect in national popular vote numbers as well).
POD 2: Hubert H. Humphrey accepts President Johnson's advice to add a moderate Southerner to his ticket - chooses former North Carolina Governor Terry Sanford. This helps him in North Carolina, but nowhere else.
Scenario One: Electoral Draw
North Carolina: Wallace improves over Nixon, some more voters shift from Nixon to Humphrey to support home state running mate: Humphrey/Sanford 552,448 (34.8%) (+5.6%) Wallace/Chandler 542,923 (34.2%) (+ 3%) 492,123 Nixon/Agnew (31%) (-8.6%)
Kentucky: Chandler's presence in his home state draws more Nixon votes to the Wallace/Chandler ticket: Humphrey/Sanford 392,792 (37.2%) (-0.5%), Nixon/Agnew 391,736 (37.1%) (-6.7%), Wallace/Chandler 268,197 (25.4%) (+7.2%), Other 2,843
Missouri: Same effect as Kentucky, though less of a swing as Chandler is not native to the state: Humphrey/Sanford 772,657 (42.7%) (-1 %), Nixon/Agnew 761,800 (42.1%) (-3%), Wallace/Chandler 275,044 (15.2%) (+4%)
Tennessee: The choice of Chandler adds momentum to Wallace's ticket and he draws from the other two: Wallace/Chandler 486,961 (39%) (+5%), Nixon/Agnew 422,032 (33.8%) (-4%); Humphrey/Sanford 339,624 (27.2%) (-1%)
South Carolina: Highest pro-Wallace climb in a conservative Southern State with deep Democratic roots and historic antipathy to the Northern Republican Party (they do not view Spiro Agnew as a 'Southerner'): Wallace/Chandler 295,473 (44.3%) (+12%), Nixon/Agnew 220,761 (30.1%) (-8%), Humphrey/Sanford 170,747 (25.6%) (-4%), Other: 4
