Counting the two Independents as Democrats, who they caucus with:

Top 25 states: 2 Democrats - 52% 2 Republicans - 40% Split - 8%

Bottom 25 states: 2 Democrats - 36% 2 Republicans - 60% Split - 4%

Top quintile: 2 Democrats - 50% 2 Republicans - 40% Split - 10%

2nd quintile: 2 Democrats - 60% 2 Republicans - 30% Split - 10%

Middle quintile: 2 Democrats - 40% 2 Republicans - 60%

4th quintile: 2 Democrats - 30% 2 Republicans - 70%

Bottom quintile: 2 Democrats - 40% 2 Republicans - 50% Split - 10%

The very top and very bottom are a 55% to 45% split in either direction. It's not a heavy skew, a single party flip in the quintile from the majority to the minority would make it 50/50 even. Those quintiles cancel each other out when voting on party/caucus lines. It's actually the 2nd and 4th quintiles that have the biggest skews. Democrats take the 2nd quintile while Republicans take the 3rd and 4th.

I definitely appreciate your measurements, but I think your analysis is off.

The top & bottom quintiles don't cancel out, but rather support the same trend, which is that Republicans have more voting power per capita.

That said, I am surprised that the top & bottom quintiles are nearly balanced. I'll have to look up which bottom quintile states have Democratic senators.

Thank you for that.

I agree, the data does indeed show that Republicans have more voting power per capita, as they have advantages in the bottom 3 quintiles. However, I don't think the correlation of population to party (at the state level) is as extreme as some try to portray it. There are high population Republican states as well as low population Democratic ones. Vermont, Rhode Island, Delaware, and New Hampshire are Democratic states in the bottom quintile.

The top has 11 Democratic votes and 9 Republican votes. The bottom has 9 Democratic votes and 11 Republican votes. If they all vote on party lines it's a tie. So it's really the middle population states that give Republicans their current edge.

It's a frequent criticism that smaller states have outsized representation relative to their population. The US is not alone in this, the EU also has the same characteristic. Germany, the most populous, has over 150 times the population of Malta, the least populous, but only 16 times the amount of representation in parliament (96 MEP vs 6 MEP). By comparison, the largest state, California, has 37 times the population of the smallest, Wyoming, but 18 times the representation in Congress and the electoral college (54 vs 3). Granted, it's not an apples to apples comparison as the votes are divided between houses and the relative power of the EU vs the US federal government but it's a comparison nonetheless.

It's a compromise when trying to form a union of political entities that differ so greatly in size. The smaller entities obviously give up some sovereignty to their larger counterparts. The larger ones seem to have to have to reciprocate in a meaningful way to keep a voluntary union.
