As Donald Trump has continued to surge in the polls, there's been a media blackout of Democratic presidential candidate Sen. Bernie Sanders, despite the fact that recent polling shows Sanders beating every single Republican frontrunner in a general election.

Here's more on that from Hartmann:

Symone D. Sanders, Bernie Sanders Campaign, joins Thom. According to recent polls - Bernie Sanders would beat every single Republican frontrunner in a general election - and he'd win by more than Hillary Clinton would. The numbers are in - and the media is still snubbing the longest serving independent in Congress - and his campaign for president.

According to a report at "Tyndall Report" Donald Trump's campaign has received 234 minutes of coverage from all the major network nightly news shows on ABC - CBS and NBC. But somehow - Bernie Sanders has only received a total of 10 minutes of coverage - from all three networks - combined. Sanders got 6.4 minutes of coverage from CBS Evening News -- as opposed to 65 minutes for Trump.

That breaks down to 2.9 minutes of coverage from NBC Nightly News for Sanders - as opposed to 88 minutes for Trump and Sanders got only 20 seconds - 20 SECONDS - from ABC World News - as opposed to a whopping 81 minutes on ABC World News. So - what's going on here? Is this evidence of how badly the corporate media wants to only support candidates who are strictly commercial and corporate friendly? Or is this just the end result of a media that's more concerned with entertainment and ratings than covering policies and politics?

And from Common Dreams: As Trump Surges, New Polls Underscore Corporate Media's 'Bernie Blackout':

New Wall Street Journal/ NBC News polling numbers out Sunday showed that Donald Trump continues to lead the wide and varied Republican presidential field and—despite increasingly inflammatory rhetoric—reached a new high with 27 percent support.

The latest survey comes on the heels of an analysis by the Tyndall Report which showed that media coverage of Donald Trump eclipses that of all his rivals from both parties.

According to the study of nightly news programs on NBC, CBS and ABC, Trump has received more network coverage than all the Democratic candidates combined and accounts for 27 percent of all campaign coverage thus far.

What's more, there appears to be a concerted "blackout" of news about Bernie Sanders, despite similar voter support.

As Eric Boehlert at Media Matters for America pointed out this week, "The network newscasts are wildly overplaying Trump, who regularly attracts between 20-30 percent of primary voter support, while at the same time wildly underplaying Sanders, who regularly attracts between 20-30 percent of primary voter support." [...]

In a campaign statement, Sanders' campaign manager Jeff Weavers said that media channels were ignoring the progressive candidate because his campaign is an affront to the corporate-dominated system.

"The corporately-owned media may not like Bernie’s anti-establishment views but for the sake of American democracy they must allow for a fair debate in this presidential campaign," Weavers said. "Bernie must receive the same level of coverage on the nightly news as other leading candidates."

The campaign has even begun a petition calling on corporate-owned channels to "start covering Bernie."

Commenting on the stark divide on Sunday, columnist Juan Cole suggests that with Trump's anti-Muslim and anti-immigrant messaging propelling some followers to take drastic action, the corporate media may be posing a "danger to society."

Cole writes:

What better for corporate news. You pretend there isn’t a candidate in the race addressing growing economic inequality or the woes of the working class. You put all the spotlight on someone who insults and even incites against Mexican-Americans, African-Americans and Muslim-Americans. It is a tried and true tactic of the American business class to keep the workers and middle class divided by playing up minor ethnic issues. The end result, however, is fire-bombing of mosques and attacks on minorities and other white hood phenomena familiar from past epochs of American history.

For his part, the U.S. Senator from Vermont continues to lead Democratic frontrunner Hillary Clinton in New Hampshire with 50 percent of likely Democratic voters in the state, compared with her 40 percent, according to the latest CNN/WMUR tally. Meanwhile, a Fox News survey released on Sunday found Clinton leading Sanders in Iowa 50 to 36 percent.
