When moderator Erin Burnett (Cecily Strong) turned to Sen. Kamala Harris (Maya Rudolph) she was told, "That little girl you just introduced was me." And Sen. Elizabeth Warren (Kate McKinnon) assured voters, "America, I'm fun. I'm like a brisk walk."

As television, it was hilarious. But for Democrats it should be alarming, right down to Erin Burnett's sign-off: "And those are our choices, America. Good luck."

With Trump and his cohorts digging themselves into what appears to be their deepest hole yet over matters involving Ukraine, Democrats should be cruising. Instead they have a clutch of flawed front-runners who seem strangely unsuited to the moment.

Bernie Sanders, who offered an exciting alternative to Hillary Clinton in 2016, now seems too much a parody of himself and too risky for voters who want stability in the White House without the drama. Elizabeth Warren sends vibes to some voters that remind them of Clinton—not because she's a strong woman, but because she appears at times to be acting the part, angling to be someone she is not.

Joe Biden is a fine man whose best years are behind him. He's a few flubs away from sending his supporters scurrying for someone else. Kamala Harris signals voters with her recurrent clarifications and policy revisions that she's not ready for prime time. Pete Buttigieg strikes many, myself included, as the most articulate, thoughtful candidate in the field. But a 37-year-old mayor of a medium-sized city who happens to be gay is not the sure thing Democrats are looking for.

For months it seemed Biden was the answer. Yet, as Harrelson's Biden clarified: "I'm like plastic straws. I've been around forever. I've always worked. And now you're mad at me?"

Every politician has frailties that can be exploited in comedy. Even the beloved John F. Kennedy was lampooned by a comedian named Vaughn Meader, whose 1962 album "The First Family" mocked JFK's New England accent and joked about his "rubber ducky." It was funny but loving; it scratched the surface without exposing any deeper truths.

I imagine the scene in SNL's writers' room last week was not unlike that in the bunker where Trump strategists are holed up. With the current Democratic field, the skits—and the attack ads—seem to write themselves.

The next debate, on CNN October 15, will be a critical test. With as many as 12 candidates on stage it will probably be easier for the front-runners to stumble than it will be for lower-polling candidates to rise up. Yet, if Democrats are to find a viable candidate outside the top tier, time is running out.

Maybe it's fortunate that "Saturday Night Live" will be on a brief break and won't do a show immediately after the October debate. Funny as it might seem, the state of the Democratic field in 2020 is no laughing matter.
