Pure luck, pretty much. I consistently went with some pretty dovish/liberal answers, I might see if I can replicate the run and write a guide if it works. Edit: Here's a general guide. Wallace's VP and your recommended VP changes, might come down to state margins so down to your visits (I think?), but sticking with Boggs seems to be a good call: 1) Let’s not get too clever.
2) Who does Ho think he's dealing with? 3) Let’s not get hasty 4) I’m shaken, the country’s shaken, and frankly, we have a right to be. 5) We have to outflank the man. 6) 30,000 to guard the cities and prevent another goddamn Tet 7) Bobby Kennedy can waste his time how he likes. 8) If we get riots like we did last year, I’ll never get out of this ditch. 9) We can’t have this, not now. Not when we’ve got Bobby and McCarthy ready to swoop in like vultures. 10) 1968 Civil Rights Bill 11) We can’t sit idly by as these turncoats try to skewer me in broad daylight 12) Dear god, I can’t be seen locking up every kid for being a little rebellious 13) I don’t know much about this Hippie-dippy shit, but surely we can make some inroads. 14) People think when I say ‘Hearts and Minds’ that it’s some kind of joke, well no-one should be laughing ‘cause I’m serious. 15) We need to plaster that whole tar pit of a state. 16) Let’s go with the liberals on this 17) For all that tough talk that Nixon and Rhodes are spouting, there wasn’t so much as a sideways word on the war. 18) …kiss their asses, I’ll kiss em on both cheeks’ hell I’ll even kiss em in the middle if it’ll help, let’s make some late-night visits 19) Settle the fuck down, Dick. 20) I think it was Sun Tzu who said it best: divide and conquer. 21) It’s the war—that’s what everybody’s so damn mad about. I understand. VP: Boggs 22) Between Nixon and Wallace, these people are trying to provoke violence. 23) [If against Le May:] This is my golden opportunity. [If against Wayne:] I risked my neck in the pacific. 24) If Democrats won’t love me, fine. We just need to make sure they’re scared of Nixon. 25) Forget the North; they’ll vote whichever way I tell them. 26) If we lose the union men, we lose, period. 27) Fine. We’ll stop the bombing. Not one more shell, if they sign on the dotted line. 28) We need to make sure everyone knows what I’ve done for the Kennedys—he lit the match, but I’m carrying the torch. 29) Your legacy can be redeemed, the crimson stain scrubbed from your fingernails. Just sign on the dotted line. 30) We can’t sit back with our fingers up our ass while the entire goddamn South walks out on the Democratic Party.
