[1] There is a relevant thread on this scenario from this very site:

[2] The Democrats had control of 26 state delegations, who would likely vote for Humphrey. Even if their state went for Wallace, I think it’s unlikely that southern Democrats would vote for him, as doing so would likely mean a Romney victory. While the House Dixiecrats opposed civil rights, they were still Democrats (Democrats were the dominant party in the south until the 90s). Five states had split delegations: Oregon, Montana, Illinois, Virginia, and Maryland. All except Maryland voted for Nixon in OTL (and Romney in ATL). I assume each state delegation would vote for whoever won the state, though that is not a given. This scenario is explored here:

[3] I assume Muskie would have to recuse himself, so totals add to 99.
