The presidential race that is shaping up will be a landmark for American media, exceeding even the pro-Obama bias of 2008 and 2012 – something that would have seemed impossible at the time of those races.  But that was before Donald Trump and Ted Cruz became the likely alternatives for the GOP nomination. Each man, in his own way, is anathema to the progressives in the media, while Hillary Clinton evokes nothing but warm protectiveness, especially from female neoprogs.

In a remarkable display of a complete lack of self-awareness, Carol Costello of CNN shamelessly prodded a pro-Sanders guest three times to say that Sanders should now “cool it” and stop attacking Hillary Clinton. David Rutz of the Free Beacon captured the moment:

Previewing her segment with Clinton supporter Maria Cardona and Sanders backer Jonathan Tasini, Costello brought up the continued contentious rhetoric between the two campaigns and pointed out Donald Trump had quoted Sanders’ charges that Clinton was not “qualified” to be president.

“So, Jonathan, should Bernie Sanders cool it with the attacks?” Costello asked.

Tasini launched into a discussion about addressing voting problems in New York and across the country, but Costello wasn’t interested.

“No, no, and I do think that most voters on both sides think that you’re right, that we do need to look at these things,” Costello said. “But it is what it is at the moment, and Hillary Clinton and Bernie Sanders are running to become the Democratic nominee. So I’ll ask you again, Jonathan, should Bernie Sanders cool it?”

Costello went on to plead that both candidates stop criticizing each other (because, after all, now is the time to defeat the Republican):

“But Jonathan, we’re at a fork in the road,” Costello said. “We’re at a fork in the road.”

“Let me finish,” Tasini said.

“So, maybe both candidates should cool it,” Costello said.

See for yourself.

Costello has already made clear her contempt for Republicans, in an infamous tweet calling an embarrassing audio of Bristol Palin, “quite possibly the best minute and half of audio we've come across in a long long time”
