My view of the winners and losers in Tuesday night’s Democratic debate is pretty much the same as what I’ve seen from other observers. Hillary Clinton won with a strong, polished performance (and was likable enough). Bernie Sanders was uneven but had his moments. And Martin O’Malley emerged as the only real alternative to the two front-runners, as Jim Webb fizzled and Lincoln Chafee popped.

So let me turn instead to the biggest loser of the debate: CNN, which for whatever reason just can’t seem to get its act together. Moderator Anderson Cooper is a smart, authoritative presence, but during the debate he was both too authoritative and too present. He interrupted constantly. Every candidate’s answer, it seemed, played out against a backdrop of Cooper trying to get him or her to stop. Sometimes a strong hand is needed. But politics ain’t beanbag, as Mr. Dooley instructed us. Let them mix it up.

Far worse was CNN’s weirdly tone-deaf wallowing in racial and gender stereotypes. It was well into the debate before we heard from a black journalist, Don Lemon. So naturally he drew the assignment of asking about the Black Lives Matter movement. As Beat the Press contributor Justin Ellis of the Nieman Journalism Lab tweeted:

"I want to talk about race in America. And here's Don Lemon." Annnnnnnd I'm out

Later on, the first question about immigration came from — yes — Juan Carlos Lopez of CNN en Español. After that, someone on Twitter wondered sardonically if Dana Bash had been designated to ask about abortion rights. Not quite. But Bash did ask Clinton about family leave, which prompted an exchange on the challenges faced by working mothers. Hey, CNN: minority and female journalists are capable of asking about gun control and campaign-finance reform, too.

It was not a great night for new media, whether you’re talking about new new media (Snapchat), old new media (Twitter) or ancient new media (Facebook). Facebook actually co-sponsored the debate, but I couldn’t find anything especially compelling. I did run across one amusing video on CNN’s Facebook page (flagged by local social-media guy Steve Garfield) on a behind-the-scenes look at debate preparations. As it ended, the host, Chris Moody, turned toward the camera and said, “It’s been real. Thanks, Snapchat.” Realizing his mistake, he turned to others and repeated his mistake. “I said Snapchat.” A pause. “Bye, Facebook. Sorry, Facebook.” To quote a famous debate moment: “ Oops.

Twitter is still the go-to place for real-time conversation during a news event. But I kept checking a running story on the debate that was posted in Twitter’s brand-new Moments section, and what I found was pretty weak. It was too mainstream; tweets were posted in chronological rather than reverse chronological order; and there was little of the sense of unexpected discovery that draws me to Twitter. As described by Mathew Ingram of Fortune, Moments is supposed to be a curated news experience aimed at users who find “real” Twitter too confusing and time-consuming. Maybe it will catch on, but I just didn’t see much value in it.

As for Snapchat, well, better luck next time? At a recent appearance at Harvard’s Shorenstein Center, Snapchat’s chief journalist, Peter Hamby, waxed enthusiastic about the Live Stories the mobile-only service posted after the two Republican debates. Maybe we’ll have to wait until Wednesday, but as I write this — around midnight on Tuesday — there’s nothing. And CNN’s Snapchat channel is still devoted entirely to a preview of the debate.

Again, we’ll have to wait for Wednesday. But I could sneak back downstairs and watch post-debate reaction on my old-fashioned TV. Isn’t online media supposed to offer a sense of immediacy that legacy platforms lack?
