If Clinton loses in 1992, I imagine that the bulk of the blame would be pinned on him personally. It's easy to look the other way on moral and ethical failings when your guy is winning, but if he lost that'd be a very different story. Plus the DLC was strong and would push the "It was Clinton, not Clinton's politics, that caused us to lose" argument.
How does Bush pull out the win in 1992? From July to November there wasn't a single poll that had HW ahead or even very close. Maybe he pressures Powell into joining the ticket? I ask this because what the GOP side is like is probably going to have an impact on who the Dems nominate.
The 1996 GOP Primary, the party was aware that Quayle wasn't the strongest candidate. Dole might be able to clinch it, but a lot of his seizing the nomination OTL was because of how few other people were running. If Powell is Bush's VP in 92, maybe he'd be nominee. I'd put good money on the Draft Powell movement being stronger (because the GOP recognizes how tough a fifth term in power would be) or Jack Kemp having a strong shot due to having been a cabinet member for 8 years. Maybe Kemp gets a bigger and more important cabinet role in the second term. I
But looking at names listed in the poll...
Biden? Gaffe-prone. Bradley? Maybe. Jerry Brown? Too weird. Bill Clinton? Nope. Ya blew it buddy. Mario Cuomo? Possible, but he had his reasons OTL for not running including NY State not doing too hot. Paul Wellstone? Too liberal AND not a big enough national following (Cuomo at least had a big national following). Dick Gephardt? I'm not sure. Moderate and midwestern could work, but was he all that great a campaigner? Al Gore? Stained by Clinton. Ann Richards? You get a southern gal with a liberal streak, which is a decent combo. Tom Harkin? Not that big a name. Bob Graham? How big a name was he? I can see it sort of, but I wouldn't put him high on the list. Sam Nunn? He will have some flack after a southern moderate just lost an election, but he also was a pretty respected guy on his own merits and wouldn't have Clinton's ethical failings. Jesse Jackson? Hymietown. Bob Kerrey? Relatively young, midwestern, sort of liberal but not too liberal, lost his legs in war. Not a bad call. Chuck Robb? Idk.
It's a bit of a cliche on this forum, but Richards threads the needle pretty well in terms of exciting liberals but also catering to some less liberal demos. If you wanna try the two southerners thing again, I think an Anne Richards - Bob Graham Ticket would be very strong in a general election.
