As per usual, I'm genuinely confused when it comes to the US politics. The way I understood this tally (source): Southern Republicans: 0–10 (0–100%) Northern Democrats: 145–9 (94–6%) Northern Republicans: 138–24 (85–15%) Northern Democrats gave 94% 'yey' (in favour) for the bill to pass while 100% Southern Republicans (all 10 of them) voted 'ney' (against) and more Southern than Northen people voted against (87 + 10 = 97 > 9 + 24 = 33). It's about the same for the 'Senate version'. Doesn't it mean the opposite of what you wrote?94% of Republicans supported this while no Democrats did. The 15th Amendment, which gave the right to vote to all native born had 100% of Republican support and no Democrat.Sep 3, 2016
Southern Democrats: 7–87 (7–93%)
