Since January, Fox News has seen a precipitous drop in its reputation amongst its mostly conservative viewership — falling to 50th place on a list of brands most trusted by Republicans over the past two years.

In 2014, the most dominant cable news channel was the 10th best-perceived brand by Republicans, according to AdAge. But in a YouGov Brand Index survey released at the end of February 2016, the perception of Fox News among Republicans had “declined by approximately 50 percent since January of this year” — to a three-year low.

And in a just-released 2016 YouGov BrandIndex ranking, Fox News’ positionplummeted to outside of the top-20 for the first time.

YouGov BrandIndex interviews 4,300 people each weekday from a representative U.S. population sample. Respondents are drawn from an online panel of more than 2 million individuals and survey results are sorted by respondents’ self-reported political affiliation: Republican, Democrat or Independent.

While Fox News’ ratings have remained high throughout the entire campaign season, its brand began to drop during the feud with Donald Trump.

Following the first GOP primary debate hosted by Fox News, the GOP nominee was set off by a question from moderator Megyn Kelly and went on to attack the network that had hosted him for weekly appearances.

Trump’s feud with Kelly tarnished the networks’ perception amongst viewers who suspected an anti-Trump bias. And while Trump still found safe refuge at “Fox & Friends” and even had Fox News host Sean Hannity appear in a campaign ad on his behalf, the blatant boosting alienated supporters of other Republican candidates.

Then one of the network’s most veteran female anchors accused former Fox News CEO Roger Ailes of sexual harassment.

After Gretchen Carlson filed a blockbuster lawsuit against the Fox News boss, the network saw its biggest shake-up with the retirement of longtime host Greta Van Susteren and the ousting of Ailes — who went on to join the Trump campaign as an adviser.

So, just as a Fox News host was selected as a presidential debate moderator for the first time ever, its former head was prepping Trump for the debate.
