Hundreds of hyperpartisan sites are masquerading as local news. This map shows if there’s one near you.

The growth of partisan media masquerading as state and local reporting is a troubling trend we’ve seen emerge amid the financial declines of local news organizations. But what do these outlets mean for journalism in American communities?

Using previous research and news reports as a guide, we’ve mapped the locations of more than 400 partisan media outlets — often funded and operated by government officials, political candidates, PACs, and political party operatives — and found, somewhat unsurprisingly, that these outlets are emerging most often in swing states, raising a concern about the ability of such organizations to fill community information needs while prioritizing the electoral value of an audience.

We found that while left-leaning sites prioritize statewide reporting, right-leaning sites are more focused on local reporting, suggesting different strategies for engaging with targeted audiences and indicating the potential for these sites to exacerbate polarization in local communities.
