Was that supposed to be some sort of mic drop?
The 13th Amendment to ban slavery in all America passed by a vote of 119 to 56, just barely getting over the 2/3 threshold. Do you know how many of those Representatives actually held that stance? If everyone had voted their actual stance, then it wouldn't even have reached 50%, much less 2/3rds.
Same with the Voting Rights Act and the Civil Rights Act. Plenty of politicians voted for civil rights who were NOT elected by their constituents to support civil rights, nor did they necessarily believe it themselves.
I'm not going to sit and wait for every congressman's conscience to chance in order for shyt to get done, because politicians are generally a$$holes. I'm happy with every other bit of possible pressure being applied to them too.
