ITTL Wallace is much more moderate on the race issue, and focuses mostly on the Vietnam War, leaving him very popular with the American people. If you wish I could change it for you, but he has Ronald Reagan as his running mate and the Buckleys campaigning in the northeast, plus he's been very uniting in his choices for appointments, bringing American conservatives together.
No need to change the map because of me: it's your work, do what you want with it. My qualm is the
magnitude of Wallace's victory, that's all.
Moreover, I don't think Wallace would govern as conservatively, if he was elected President - which is inferred in this timeline. He was a Democrat of the New Deal mold first and for most; in 1968 he campaigned for extra funding for social security and Medicare. He was a bigot, second; a champion of 'law and order', third. . .though not necessarily in that order.
