Campaign finances are becoming a prominent issue in today’s elections. We have candidates like Jeb Bush who are receiving record breaking amounts of donations from private citizens and private companies alike. On the other hand we have candidates like Bernie Sanders who only receives small donations from citizens. Regardless of your opinion on which end of the spectrum candidates should behave toward campaign donations, they are nevertheless an important part of US elections. When discussing campaign donations it is almost always about presidential candidates, but what about our legislators. They only time I ever heard about donations to legislators is when there is a huge scandal. Do they pull in as much money as presidential candidates? Do they receive more money from the average citizen or the average corporation? Do legislators of a certain party pull in more than another?
To achieve this I needed data on campaign donations for all the federal legislators. Luckily for me I am not the first to look for this data. There are quite a few places to go to for this information, but I wanted a place with an easy to understand API and something reliable. This led me to followthemoney.org. Here there is a very soft “API”, but nevertheless super useful and easy to parse. I took the data for all legislators from the past 5 years for any candidate that ran for either the Senate or the House of Representatives. Using their API, I exported their data in csv format. From there the preprocessing and the analysis was all preformed in python (anaconda distribution).Before we jump into the analysis we need to know a little more about campaign contributions themselves. There are federal contribution limits imposed to limit how much people (and corporations, parties, PACS, etc..) can donate. There are a few ways to get around these limits however and recent legislature that has helped to facilitate that.



That’s much better. As you can see this is obviously not a population map. States like NY, NJ, MA, and CA are not top tier, but rather toward the bottom. Interestingly enough, states that have less people in them seem to have much greater donations per person, Alaska is a notable example. Why do these states get way more contributions than others? One possible explanation are that some of theses states are swing states. Swing states (like New Hampshire above) are very closely divided between the Republicans and the Democrats. These states should naturally garnish more donations as the races should be more exciting and volatile. In coarser terms, campaign money is more valuable in these states.
Before we go any further, we have to go into whose donating, lets take a look nationwide as to who is donating the most. Is it mostly large sums, or small donations?PEOPLE, PACS, AND THINGSSpeaking of small donations, who actually donates to campaigns? I personally have never, my naïve and uninformed idea of campaign donations are just giant faceless corporations throwing money at candidates. Let’s take a peek at average joes like you and me and how much they spend. Below you can see two maps of the US, one for 2012 and one for 2014. Hover over each state to see which citizen donated the most and how much they donated, the color scale lets you compare states to each other.Now what about those big faceless corporations. Here are two more maps, however these are only for the year 2014. The map on the left shows the the top Industry for that state the chart on the right shows the top ten Industries that donate the most nationwide.
Again we have what looks to be a population map. It seems like states with the most people have the highest individual donators whether from citizens or corporations. One thing that stood out to me were the biggest donors. Real estate and medical professionals we the top players in most states. Much less surprising was that Oil & Gas donated the most where, you guessed it, there is Oil & Gas.
Finally, what about groups who donate based on different ideology? Some examples of these groups are pro-Israel, Pro-Life/Pro-Choice, environmental policy as well as many others. The bar chart on the left shows a nationwide average of which ideologies get the most money. The map on the left shows the most popular ideology per state.PARTY FOULSo far we have skipped over the two most important groups in American politics, the Republicans and the Democrats. How do the parties compare? Seeing that the country is pretty divided on party allegiance I’d expect donations to each party be relatively the same. One thing I’d also expect is that third party candidates don’t pull in even the same magnitude as the two major parties.

Well that seems about right. Democrats and Republicans pull in around the same amount each year, while third party candidates are not even close. This was to be expected as third-party candidates rarely have the same pull nor presence as candidates from the two major parties.Now what about statewide. During presidential elections most states are glazed over. This is because they are usually deeply entrenched in one party of the other. Below is a map of which party got each states electoral votes. Next to that is which party got more money in the 2014 elections.

from: Politico.com
The first graph from Politico shows which party each state voted for. The one below is which party received more donation in each state. The two maps look quite similar. Both the east and west coast mirror each other to an extent. The midwest also aligns with donations. Donations to legislators in each state may be a good predictor into where the electoral votes end up. Or, more possibly, states that were going to vote for a certain party donate to that party more.
Some states receive a lot more attention than other when it comes time for presidential elections. Currently I am only looking at federal legislator’s donations, but I wonder if they reflect presidential politics as well. Certain states I will refer to as swing states. These states are not as deeply entrenched as others. The swing states for 2014 were: Nevada, Colorado, Iowa, Wisconsin, Ohio, New Hampshire, Virginia, North Carolina, and Florida. The map below highlights states that have the closest spending between the Democrats and the Republicans.Most of the swing states have very similar donations between the two parties. Swing states like Virginia, Florida, and Nevada have very close donations totals. Virginia actually has the closest out of all of the states. On the other end, states like California, Texas, and New York have the greatest difference in donations. This makes sense as these states are deeply entrenched in one party, just look at Texas the donations are completely lopsided. There is some good news in this map. Most states are relatively close when it comes to donations to both parties.
MONEY MONEY MONEY MONEYPolitical Donations are a critical component of the United States government. Looking at the donations many of my previous assumptions were confirmed and many were discredited. However, one must have a critical eye on the data presented. The analysis is only as good as the data collected. I believe it is integral to have reliable and vetted donation data as it holds many insights. I’d like to thank followthemoney.org for their data and commitment.
