Journalist and author Mark Halperin on Monday mocked the “unscientific” claims of liberal media bias from conservatives. With All Due Respect guest Donny Deutsch derided the 2016 campaign assertions as “conspiracy theories." After playing a montage of conservatives on Fox hammering journalists for coverage of Donald Trump, Deutsch seethed, “It's preaching to their audience which, A, loves conspiracy theories. I mean, they're talking to their audience.”

Bloomberg editor Halperin played a montage of complaints of liberal bias and derided, “But I think it is so diluted. It is so unscientific and so un-rigorous, so off the point of [Trump] needing a comeback.” He included an example of Fox and Friends hosts discussing a study by the Media Research Center’s Rich Noyes.

In the clip, Fox host Steve Doocy suggested people “look at the media bias and you look at the Republican vs. Democratic conventions."

Far from being “un-rigorous,” the MRC study found:

During the first two days of the Democratic convention, various speakers called Donald Trump a con man, a fraud, a bigot, and a racist; someone who “cheats students, cheats investors, cheats workers,” who “rejects science” and would take America “back to the dark days when women died in back alleys.” Trump’s policies and rhetoric was described as “cruel,” “frightening,” “deceitful,” “deeply disturbing” and “ugly.” He was someone who promoted “racial hatred,” who had “hate in their heart,” and was “making America hate again.” But while the media routinely attacked the Republicans during the GOP convention for negative attacks on Hillary Clinton, the Democrats’ attacks on Trump were given a pass. MRC studied ABC, CBS, CNN, MSNBC and NBC’s coverage from 9pm to midnight during the first two nights of each convention. During the GOP convention, journalists scolded the Republicans for negativity 63 times; for the same time period during the Democratic convention, viewers heard only five such comments from reporters, a more than 12-to-1 disparity.

Deutsch helpfully explained the disparity this way: “Maybe there were more negative mentions at the Republican convention because it was horrible and depressing. It was a lynch mob.”

Halperin chided, “The Fox and talk radio news loop, it's death to them.”

How could conservatives the find 2016 coverage to be slanted?
