Mapping Opposition to the GOP Health Care Bill by Congressional District

By Matt Stiles | | Topics: Demographics, Policy & Politics

The legislative failure of the GOP’s replacement for Obamacare has been widely reported, obviously, but I remain interested in one bit of polling noted this week by FiveThirtyEight.

The polling firm YouGov estimated the legislation’s unpopularity by congressional district. The bill itself was quite unpopular, it turns out, even in conservative districts, as FiveThirtyEight’s Nate Silver reported.

Thanks to DailyKos Elections, we can also marry the data with President Donald Trump’s vote share in each district.

I’ve been experimenting with maps in D3.js, and I hadn’t yet tried congressional districts. So this seemed like a perfect opportunity, even if thematic maps aren’t particularly useful in this context (because congressional districts vary in size geographically, such maps can be misleading).

Case in point: The national map of congressional districts, with Republicans in red and Democrats in blue . As we all know, Democratic districts tend to be smaller in terms of area and clustered in more densely populated places. So they don’t get a particularly fair representation on a map:

Consider these two treemaps. This first shows members of the U.S. House by party (with some vacancies in gray). Shapes are sized based on the average population of each congressional district: roughly 710,000 people, give or take five percent. The House has 237 Republicans, 193 Democrats and five vacancies. There’s clearly a red majority, but it’s relatively close:

This treemap, however, shows the geographic area in square miles. Now you see the distortion:

OK, you get it. So let’s see how the health care opposition looks on maps.

Charting Partisan Polarization in Congress

By Matt Stiles | | Topics: Policy & Politics

The Fix today has a post about the newly released digital version of Vital Statistics on Congress, a partnership between between a few think tanks that contains reams of enlightening data about the institution.

Among the more interesting examples is a table showing the partisan polarization over the years. Chris Cillizza’s take:

There is, really, only one thing you need to understand if you want to see why Congress doesn’t do much of anything these days. And that one thing is this: We are living in a time of historic polarization between the two parties.

It’s clear from the chart in the report that the parties are as far apart as they’ve been in the modern era:

Charting Days Members of Congress Spend in ‘Session’

By Matt Stiles | | Topics: Policy & Politics

Time is winding down on another year of congressional business. How much time have representatives and senators worked this year compared to the past?

Senators, on average, were in session about 155 days a year over the last three decades. This year: 169. Representatives worked less: about 138 days, on average, over that time. This year (as of Dec. 20): 170. 

To be sure, governing America is different than the average American job. But how much might they have been expected to work compared to the rest of us? Some context

There are 365 days per year and about 104 weekend days. This is 260 days. If you subtract the 10 legal bank holidays taken this would be about 250 business days a year.

This chart, created from Library of Congress records, shows how many days each chamber was in session over the last three decades. The Senate’s top year was 1995, after Republicans took over the House in the “Contract with America” sweep (209 days). The House’s top year was 1979 (173 days):

Visualizing Congress

By Matt Stiles | | Topics: Uncategorized

I just discovered the promising Clear Congress Project today, which visualizes legislative data by political party and other other variables in real time. A mission statement from the developer: 

With the expansion of the Internet and computing technologies, the amount of data generated and recorded has increased exponentially. Recently, government initiatives, non-profits, and news organizations have created easily accessible sources for the large amount of data created pertaining to government institutions. However, government organizations too often mistake access for transparency and news organizations have been reluctant to adopt innovative news delivery formats better designed for their new role as producers and distributors of not just stories but also data. Clear Congress Project (CCP) leverages real-time data sources and information visualization techniques to serve as a model that realizes transparency as a process beyond data access and offers a new format for news distribution.
