'Alternate reality': Republicans who don't watch Fox News have dramatically different views than Republicans who do

Republicans who don't watch Fox News have markedly different political views than Republicans who do, according to a new poll.

Nearly eight in 10 Republicans -- 78 percent -- who watch the conservative news network say President Donald Trump is the most successful president in history, compared to just 49 percent of Republicans who don't watch Fox News, according to poll results reported by The Daily Beast.

The results were provided to the website by Navigator, a project launched by Democratic groups Global Strategy Group and GBA strategies, and show the network's influence on its viewers.

The survey's authors say Fox News presents an "alternative reality" to its largely conservative viewers, and plays an "outsize role" in shaping the political and even scientific views for a significant portion of American voters.

For example, Republicans who don't watch are nearly twice as likely to believe climate change is driven by human activity, compared to just 12 percent of Republicans who do watch Fox News.

Nearly the same percentage of Republican Fox News viewers -- 79 percent -- who believe Trump is the most accomplished president ever also believe the FBI and U.S. intelligence agencies are trying to sabotage the president.

Slightly less than half -- 49 percent -- of non-Fox News Republicans believe Trump was the victim of such a conspiracy, and just 8 percent of registered voters who don't watch the network agree.

“Where Republican partisan affiliation and the Fox News echo-chamber overlap, there is near unanimity on the politics and even the facts defining the Trump presidency," the poll's authors say. "This is the ‘FoxHole.' What the Navigator data demonstrates is this particular segment of the public is so vastly different from the rest, it may serve progressives best to focus their attention on everyone else.”

Interestingly, the poll also found that Fox News viewers are far more aware of progressive issues, such as the Green New Deal, than those who get their news elsewhere, because the network relentlessly pillory such proposals.
