Democrats: Pass landmark legislation to give minorities political power
This is some wild erasure of impact of the Civil Rights Movement in the 60s on pressuring Democratic politicians, including LBJ himself, who was more worried about pissing off southern Democrats than passing the VRA. It wasn’t until the threat of mass civil unrest was upon them that that it was passed with bipartisan support, with 20 of the 32 Republican Senators at the time (not a typo, Dems held a supermajority of the Senate) cosponsoring the bill to prevent southern Democrats from filibustering it. It also passed the House with bipartisan support and a 333–85 vote (Democrats 221–61, Republicans 112–24).
As always it is the people, not politicians, who get the goods.
