Following on from my post prior to the election “The Rigged
System”, here I will analyze the 2016 results with an eye towards calling out
deviations from the proportional ideal. The results are incomplete as votes
are still being counted, but we know enough to draw some conclusions.
The big story of course, is the Electoral College bucked the
popular vote for the 5th time in our nation’s history. The
well-known data scientists Nate Silver and Nate Cohn expect the final tally to
be somewhere between a 1 and 2% margin for Clinton. As of today (11/17), the
count on USelectionatlas.org has the margin at 1.01%:

The bottom line here is an R-bias of 13.8 + 1.0 = 14.8%.
Now let’s look at the House, the people’s chamber. Thankfully,
the Cook Political Report has aggregated data on all 435 seats.

The bottom line in the House is an R-bias of 10.4 - 3.0 = 7.4%.
This is right in line with the 2012 and 2014 biases -- the other House
elections in this decade.
For good measure, I looked at the Senate election aggregates
as well, which is something I did not consider in my previous post. The data is
from USelectionatlas.org. California must be excluded, because they have a
different system (a free-for-all multi-party primary and a general election
runoff). Their ballot only offered the choice between two Democrats for the
Senate. The other state that needs to be excluded is Louisiana since they will
be having a runoff election to determine the winner. That said, here are the
results aggregated across the remaining 32 Senate races:

The R-bias in the Senate was 31.3 – 0.9 = 30.4%.
Not only has it shocked the world that Trump won, it is also
quite stunning and rare that Republicans have swept the coveted ‘trifecta’. But any suggested
mandate should be taken with a grain of salt. The country is much more evenly
divided than it would appear. By a significant margin (1% and rising), more
people voted for a Democrat in the White House. Similarly, the House elections
recorded a significant margin (3%) for Republicans. The Senate elections were
almost even (if California had a more normal race).
Side note: It struck me as an odd quirk of our federal system
that election data is not readily available. I found out that the raw data that
underlies every news site is made available by the Associated Press by
subscription. Thanks to the US Election Atlas and the Cook Political Report for
their work.
