Think this page is wrong?

What we are responsible for is everything else: the ownership chain, where Media Matters for America publishes from, which of our stories we have listed it on, and whether we have the right publisher at all. Tell us what is wrong and an editor reads it.
Report something wrong on this page
Anything we correct is written up in the public corrections log. We do not publish reader votes as a rating, because an unattributed rating is the thing this site exists to argue against.
Every rating on this page is a named third party’s published work, republished with its author and, where one exists, a link to it. Our own coverage record is the section we measure ourselves. Neither is a judgement of any individual report: those are scored story by story, and the reasoning is on our methodology page.
