There's no doubt that Fox News offers lively and entertaining fare, but if conservatives ever want to exert political change in this country they have to dump the Rupert Murdoch/Roger Ailes creation.

A Brookings PRRI survey on immigration offers the latest evidence of the danger posed by the Fox echo chamber on the hopes of Republicans.

It found that 25 percent of Americans believe Fox News offers “accurate information about politics and current events.” That skews well with broadcast news (23 percent) and tops anti-Fox MSNBC, which is trusted by only eight percent).

A huge chasm exists between Fox’s Republican core viewership, independent voters and Democrats.

A whopping 53 percent of GOPers give Fox a thumbs-up compared to 26 percent of indies and six percent of Dems.

Broadcast news scores much better. Twenty-two percent of Republicans believe the Big Three Networks are accurate, while 17 percent of independents and 31 percent of Democrats agree.

The poll also found that Republicans largely rely on Fox and network news as top news sources.

Democrats enjoy a broader view of the world, as they split viewership among networks, CNN, PBS, “Daily Show with Jon Stewart and MSNBC.

New Republic, which ran an analysis of the survey, posed the intriguing question: “Does Fox News Cause Ignorance, Or Do Ignorant Viewers Prefer Fox News?”

That’s a snarky way of putting it.

However, the road to the White House depends on Republicans grappling with the overbearing influence of Fox News.
