While Pew Research Center’s recent report on media polarization and the 2020 election found that many Democrats and Republicans differ from each other in their sources of news, about one-fifth of those in each party are in a more isolated kind of media bubble – getting political news in a given week only from outlets predominantly used by people who align with them politically, according to data from the Center’s Election News Pathways project. Respondents were asked if they got political and election news in the past week from 30 different sources representing a range of news media across different platforms. Based on this data, researchers calculated the political composition of each source’s audience. (See here for details about the ideological composition of news outlets’ audiences.)

In total, 20% of all Democrats and independents who lean Democratic get political news only from outlets with left-leaning audiences. Similarly, 18% of all Republicans and independents who lean Republican get their political news only from outlets with right-leaning audiences, according to the survey of 12,043 U.S. adults who are members of the Center’s American Trends Panel, conducted Oct. 29 to Nov. 11, 2019.

As noted in previous Pathways analyses, partisans in these two categories frequently have very different levels of awareness and perceptions of political events in the news.

Who are the people who choose these more politically isolated news diets? Republicans and Republican-leaning independents who get news only from outlets with right-leaning audiences tend to be older and more likely to attend religious services than Democrats and Democratic leaners who get news only from outlets with left-leaning audiences. Democrats in a left-leaning audience news bubble are more likely to be female and to have graduated from college than Republicans in a right-leaning audience news bubble.

Individuals in these two groups are naturally on different sides of the political aisle, but in many cases, they diverge even from other members of their own party. For example, Republicans who get news only from outlets with right-leaning audiences tend to be more conservative, embrace Donald Trump more warmly and rely on Fox News more extensively than Republicans in general.

The universes of outlets with right-leaning audiences and left-leaning audiences reflect another major finding from the media polarization report. Because Republicans trust and use a far smaller group of media sources than Democrats, there are far fewer outlets with right-leaning audiences than with left-leaning audiences.

Of the 30 media outlets studied, 17 were found to have left-leaning audiences, ranging from MSNBC and CNN to Politico and PBS. There are just six sources with right-leaning audiences, including Fox News, Breitbart and Rush Limbaugh’s radio talk show.

From feelings about Trump to reliance on a single main source of political news, big differences by media diet

Republicans and Democrats who get political and election news only from outlets with like-minded audiences are more likely to be conservative and liberal, respectively, than others in their parties. In all, 61% of Republicans and Republican leaners identify as conservative, but 86% of Republicans who get news only from outlets with a right-leaning audience do the same. And 45% of all Democrats and Democratic leaners identify as liberal, lower than the portion among Democrats who get news only from outlets with a left-leaning audience (62%).

Among people in these groups, there is also a stronger orientation toward certain main sources for political and election news. Republicans in a right-leaning audience news bubble overwhelmingly name Fox News (70%) as their main source for political news. Meanwhile, the most commonly named main sources for Democrats in a left-leaning audience news bubble are CNN at 21% and NPR at 18%. Among all Republicans, the portion who cite Fox as their main source of political news drops to 34%. Among all Democrats, the portion citing CNN is roughly the same, while NPR as a main source falls to 8%.

In addition to a greater concentration around Fox News as the main source of political news, Republicans in a right-leaning audience news bubble also express greater reliance on just one main source as opposed to a wider mix: 60% say they rely on their main source far more than any other source. Half as many Democrats in a left-leaning audience news bubble (30%) say the same thing.

Those in the opposite news bubbles have, not surprisingly, nearly opposite feelings toward Donald Trump. Fully 83% of Republicans in a right-leaning audience news bubble have very warm feelings toward the president (meaning they rate him between 76 and 100 on a zero to 100 “feeling thermometer,” where zero means they feel as cold as possible toward him and 100 means they feel as warm as possible). Among Democrats in the left-leaning audience news bubble, 90% say they have very cold feelings about him (ratings between zero and 24). Among all Democrats, the “very cold” number drops modestly to 81%, but among all Republicans, the “very warm” number falls to 53%. (Visit our Pathways data tool to see the full data on feelings toward Donald Trump.)

Democrats in a left-leaning audience news bubble tend to be younger, more educated, less religiously observant

Clear age and education differences also emerge between the two groups in ways that create greater gaps than in the parties overall.

About three-quarters of Democrats and Democratic leaners who get political news only from outlets with left-leaning audiences (74%) are between the ages of 18 and 49. Nearly as high a percentage of Republicans and Republican leaners who get political news only from outlets with right-leaning audiences (69%) are ages 50 and older. Democrats overall are still somewhat younger than Republicans, but to a far lesser degree (59% are ages 18 to 49 vs. 46% of Republicans).

And when it comes to education, about half of Democrats in a left-leaning audience news bubble (51%) have a college degree, compared with 22% of Republicans in a right-leaning audience news bubble. Among all Republicans, the share with a college degree increases to 29%, while among all Democrats the percentage of college grads drops to 37%.

In addition, 35% of Republicans who get news only from outlets with right-leaning audiences attend religious services at least once a week, compared with 12% of Democrats who get news only from outlets with left-leaning audiences. And while 20% of those Republicans say they never attend services, a much larger share of those Democrats – 47% – say they never attend services.

Finally, there is a modest gender gap between Democrats and Republicans who only get political news from sources with like-minded audiences. Among Republicans who get news only from outlets with right-leaning audiences, men outnumber women 55% to 45%, while women outnumber men 54% to 45% among Democrats who get news only from outlets with left-leaning audiences. Those numbers are very much in keeping with the overall gender split among all Republicans (52% male, 48% female) and Democrats (45% male, 55% female.)
