Wow! This is fantastic Hive account@gra. This is truly a post showing the power of visualization when looking for trends across massive datasets! I love how you took this very political topic and didn't at all focus on the politics, but rather on the trends! The power of this sort of visualization is it allows you to pick out "buckets" to study further how things changed, and the correlate those changes to what the underlying cause. In the case of this, why are democratc votes so variable while republican votes so very consistent. It likely speaks to the strategies that the political parties utilize for getting out the message to voters and it also explains in part the high degree of success that the republican party has had (as consistency is a key source of knowing what you have, and allows the politicians to better focus on specific areas). When voting support is more variable you can't "count" on any given place and have to spread yourself out much thinner.
