You need to realize that the 1967 democratic national convention completely changed the parties. This is important because you’re citing ‘33 Dems as if they’re remotely at all like ‘95 dems.

Democrats before ‘67 were racist as hell. Their southern strategy in ‘67 destroyed the party. Non racist republicans merged with the non racist democrats into the DNC. Racist democrats, pushing the southern strategy, left the DNC and joined the Republican party.
