Since I seem to have abandoned the "daily" thing, lets abandon the scatter plots as well.

So, I slowed down updating this, and haven't updated this in two weeks.

This is mostly because I feel I have exhausted a lot of what I wanted to talk about. Actually, I should at some point summarize what I have learned, but I don't have a lot more to say about most of what I was covering.

But, I did, on a lark, think of a question that can be used with another type of graph. And so, I present a non-scatterplot to you.

In the US election system, the president is chosen by electoral votes. The electoral system can greatly magnify a candidates success or failure. Also, electoral votes can be won by plurality, meaning a candidate can win the presidency in a landslide without actually winning any of the states by a majority. Clinton did this in 1992, only winning 9 electoral votes (Arkansas and DC) by majority, but getting 370 Electoral Votes.

So I decided to look at the history of how many Electoral Votes were won by over 60% of the vote. These show states that were won with what could be seen as a strong consensus. So from 1960 until 2008, here is the fate of both party's ability to truly capture states:
Much as with my scatterplots, the first lesson to be learned from this graph is unpredictability. The biggest lesson seems to be that holding on to Core Electoral Votes is very difficult. Even after the biggest landslides ('64, '72 and '84), the amount of core electoral votes drops. This also leads some credence to the belief that elections are more about candidates and circumstances than they are about the deep seated philosophical leanings of the electorate. Was Reagan's victory in 1984 a sign of a deep seated conservative bent in the US? According to this diagram, it would seem not, because just 4 years later, the amount of states showing a really strong commitment to support the Republican candidate shrunk down to just a few in strongholds. Of course, the same could be said of the movement from 1964 to 1968.

Another trend that actually shows up from popular political discourse in this is that some of the "Red State/Blue State" and "polarization" seems to have some evidence for it. In previous elections, one party might get a lot of Core Electoral Votes, or both parties might get none or close to none... but only since 2000 have both parties managed to have strongholds. So there is some truth to it: the current political situation is one where, regardless of candidate, Massachusetts will probably go over 60% for the Democrat, and Oklahoma will go over 60% for the Republican.

Of course, since the unexpected is expected, I bet 2012 will have some interesting changes to make to this chart.


  1. The National Popular Vote bill would guarantee the Presidency to the candidate who receives the most popular votes in all 50 states (and DC).

    Every vote, everywhere, would be politically relevant and equal in presidential elections. Candidates would need to care about voters across the nation, not just undecided voters in a handful of swing states.

    The bill would take effect only when enacted, in identical form, by states possessing a majority of the electoral votes--that is, enough electoral votes to elect a President (270 of 538). When the bill comes into effect, all the electoral votes from those states would be awarded to the presidential candidate who receives the most popular votes in all 50 states (and DC).

    The bill uses the power given to each state by the Founding Fathers in the Constitution to change how they award their electoral votes for president.

    The bill has been endorsed or voted for by over 1,775 state legislators (in 48 states) who have sponsored and/or cast recorded votes in favor of the bill.

    In Gallup polls since 1944, only about 20% of the public has supported the current system of awarding all of a state's electoral votes to the presidential candidate who receives the most votes in each separate state (with about 70% opposed and about 10% undecided). The recent Washington Post, Kaiser Family Foundation, and Harvard University poll shows 72% support for direct nationwide election of the President. Support for a national popular vote is strong in virtually every state, partisan, and demographic group surveyed in recent polls in closely divided battleground states: Colorado-- 68%, Iowa --75%, Michigan-- 73%, Missouri-- 70%, New Hampshire-- 69%, Nevada-- 72%, New Mexico-- 76%, North Carolina-- 74%, Ohio-- 70%, Pennsylvania -- 78%, Virginia -- 74%, and Wisconsin -- 71%; in smaller states (3 to 5 electoral votes): Alaska -- 70%, DC -- 76%, Delaware --75%, Maine -- 77%, Nebraska -- 74%, New Hampshire --69%, Nevada -- 72%, New Mexico -- 76%, Rhode Island -- 74%, and Vermont -- 75%; in Southern and border states: Arkansas --80%, Kentucky -- 80%, Mississippi --77%, Missouri -- 70%, North Carolina -- 74%, and Virginia -- 74%; and in other states polled: California -- 70%, Connecticut -- 74% , Massachusetts -- 73%, Minnesota -- 75%, New York -- 79%, Washington -- 77%, and West Virginia- 81%.

    The National Popular Vote bill has passed 29 state legislative chambers, in 19 small, medium-small, medium, and large states, including one house in Arkansas, Connecticut, Delaware, Maine, Michigan, Nevada, New Mexico, North Carolina, and Oregon, and both houses in California, Colorado, Hawaii, Illinois, New Jersey, Maryland, Massachusetts, Rhode Island, Vermont, and Washington. The bill has been enacted by Hawaii, Illinois, New Jersey, Maryland, and Washington. These five states possess 61 electoral votes -- 23% of the 270 necessary to bring the law into effect.
