A Deep Dive Into Party Affiliation

Democrats hold advantages in party identification among blacks, Asians, Hispanics, well-educated adults and Millennials. Republicans have leads among whites – particularly white men, those with less education and evangelical Protestants – as well as members of the Silent Generation...

The share of independents in the public, which long ago surpassed the percentages of either Democrats or Republicans, continues to increase. Based on 2014 data, 39% identify as independents, 32% as Democrats and 23% as Republicans. This is the highest percentage of independents in more than 75 years of public opinion polling. (For a timeline of party affiliation among the public since 1939, see this interactive feature.)

When the partisan leanings of independents are taken into account, 48% either identify as Democrats or lean Democratic; 39% identify as Republicans or lean Republican. The gap in leaned party affiliation has held fairly steady since 2009, when Democrats held a 13-point advantage (50% to 37%).

The Growing Blue-State Diaspora

From the New York Times

Californians have moved to Colorado and Nevada. Massachusetts natives have moved to New Hampshire. New Yorkers have moved to North Carolina and Virginia — and, of course, have continued moving to Florida.

Over the last few decades, residents of many traditionally liberal states have moved to states that were once more conservative. And this pattern has played an important role in helping the Democratic Party win the last two presidential elections and four of the last six. The growth of the Latino population and the social liberalism of the millennial generation may receive more attention, but the growing diaspora of blue-state America matters as well.

The blue diaspora has helped offset the fact that many of the nation’s fastest-growing states are traditionally Republican. You can think of it as a kind of race

How Increasing Ideological Uniformity and Partisan Antipathy Affect Politics, Compromise and Everyday Life

Republicans and Democrats are more divided along ideological lines – and partisan antipathy is deeper and more extensive – than at any point in the last two decades. These trends manifest themselves in myriad ways, both in politics and in everyday life. And a new survey of 10,000 adults nationwide finds that these divisions are greatest among those who are the most engaged and active in the political process.

The overall share of Americans who express consistently conservative or consistently liberal opinions has doubled over the past two decades from 10% to 21%. And ideological thinking is now much more closely aligned with partisanship than in the past. As a result, ideological overlap between the two parties has diminished: Today, 92% of Republicans are to the right of the median Democrat, and 94% of Democrats are to the left of the median Republican.

Today 92% of Republicans are to the right of the median Democrat, and 94% of Democrats are to the left of the median Republican
Partisan animosity has increased substantially over the same period. In each party, the share with a highly negative view of the opposing party has more than doubled since 1994. Most of these intense partisans believe the opposing party’s policies “are so misguided that they threaten the nation’s well-being.”

Democrats are from cities, Republicans are from exurbs

The first reaction many people may have when looking at a standard red/blue map of county-level election results is often "Holy crap, look at all that red!" While that huge red bulls-eye in the nation's middle is easily explained away—trees and tumbleweeds don't vote; only people do—when it's presented without disclaimers, it can help reinforce the perception that this is a "center-right nation." One of the best ways around that is with a cartogram (a map that distorts boundaries to account for another variable, like population) ... but how do we express that in a way that still looks like the United States, and not a piece of purple roadkill?

Princeton's Robert Vanderbei put together a fantastic 3-d map in 2012... that visualizes the country with blue skyscrapers towering over pink plains, reflecting the heavy concentration of votes in urban areas. However, I wanted to try going in a different direction, with a flat map, but one where the color varies by intensity according to the change in the number of votes over the years.
