Ya know I totally overlooked this chart on my first read through.

Now that you point it out I wonder if the bar chart is even the right medium for the point the creator was trying to make. Although I think your take is much clearer especially because it takes the winner value and explicitly states using the letter on the axis rather than trying to awkwardly encode it in the border of the bar.


Very interesting.
I wonder what could be done adding a third variable: the geographic position or the demographic size (admitting that you judge addition of a third variable does not overload the chart!).
The last case is simple: you can modify your final chart setting the vertical height of the horizontal bar proportional to each state population (voters) size.
The former case opens several alternatives: chart R lop-sides precints rate vs. geographic position, chart D lop-sides precints rate vs. geographic position, chart R+D lop-sides precints rate vs. geographic position.
Could a chart of R+D lop-sides precints rate (the variable you consider the most important) vs. geographic position integrate a third variable (R vs D)? I have to think about it.
About your P.S., you are right. It could be noted that the default settings can be "tricked" by adding a third series, defined by a simple =IF function.
