Five takeaways from the Democratic debate in Ohio

It was Round Four of the Democratic debates on Tuesday, with 12 candidates squaring off in Westerville, Ohio.

What were the key takeaways from the night?


Warren in the firing line

Sen. Elizabeth WarrenElizabeth WarrenWhat do Google, banks and chicken salad have in common? Final debate: War Admiral vs. Seabiscuit Biden defends his health plan from Trump attacks MORE (D-Mass.) has jumped to the top of some national polls recently, and her status as the new front-runner was underlined when several of her rivals attacked her.

They clearly see an urgent need to curb her momentum.

Kamala HarrisKamala HarrisTrump knocks idea of a 'female socialist president' Sanders hits back at Trump's attack on 'socialized medicine' Watch live: Biden participates in HBCU homecoming MORE (D-Calif.) and former Rep. Beto O’Rourke (D-Texas), joined the fray later.

Warren by no means crumbled. But she was put on the defensive as she has never been before.

On her "Medicare for All" plan, Buttigieg argued it limited choice, while Klobuchar hit her refusal to acknowledge that paying for it would almost certainly involve tax hikes.

Warren’s argument on the tax issue — that voters are concerned about overall costs, and that any tax increase would be offset because there would be no private insurance premiums — is logically defensible. But her rivals will exploit her tendency to sound evasive on the tax point.

The Massachusetts senator seemed to become more comfortable as the night wore on. And her basic position that Democrats need a platform more ambitious than one that “nibbles around the edges of the big problems in this country” has real magnetism for progressive voters.

Warren survived her first turn in the firing line competently. But everyone will be watching the polls in coming days to see whether the sustained attacks on Tuesday slowed her march.


A bad night for Biden — again

Indifferent debate performances have been a problem for former Vice President Joe BidenJoe BidenObama slams Trump in Miami: 'Florida Man wouldn't even do this stuff' Trump makes his case in North Carolina, Ohio and Wisconsin Brad Pitt narrates Biden ad airing during World Series MORE before — and he failed to break the streak on Tuesday.

The 76-year-old faded into the background for large swathes in Westerville. When he did gain the spotlight, his answers were prone, once again, to lack sharpness or punch.

Even though Biden is two years younger than Sen. Bernie SandersBernie SandersTrump makes his case in North Carolina, Ohio and Wisconsin Trump mocks Joe Biden's drive-in rallies at North Carolina event Sanders hits back at Trump's attack on 'socialized medicine' MORE (I-Vt.), he continues to sprinkle his remarks with much more anachronistic phrases. On Tuesday, he talked about people “clipping coupons in the stock market” — a reference that seemed several decades out of date.

Biden’s backers would argue that his support has always come from older, more centrist Democrats and that he is the strongest candidate to take on Trump.

But there was nothing remotely dominant about his performance on Tuesday night.


Bernie bounces back — with AOC’s help

Sanders came into this debate facing serious questions about his health. It was the 78-year-old’s first major appearance since having a heart attack.

The Vermont Independent began putting those worries to rest with a typically feisty performance. There was no sign of a lack of vigor or stamina.

But the biggest boost to the veteran democratic socialist came from outside the debate hall.

As the clashes in Westerville were winding down, The Washington Post broke the news that he would be endorsed by Rep. Alexandria Ocasio-CortezAlexandria Ocasio-CortezProgressive lawmakers call for United Nations probe into DHS 'human rights abuses' OVERNIGHT ENERGY: Democrats play defense, GOP goes on attack after Biden oil comments | Energy Dept. exempts quick dishwashers from existing efficiency standards | Ocasio-Cortez says having Green New Deal would have helped handle COVID-19 pandemic Ocasio-Cortez says Biden vote can be 'tactical' effort to support marginalized communities MORE (D-N.Y.) at a Saturday rally in Queens, N.Y.

The endorsement from Ocasio-Cortez was arguably bigger news than anything that happened on the debate stage on Tuesday. The young left-wing icon’s endorsement may not be a surprise in itself — she worked as a volunteer organizer for Sanders’s 2016 campaign — but the timing delivers a jolt of excitement to his campaign at just the right moment.

It will also come as a disappointment to Warren, whom Ocasio-Cortez had also previously praised.


Buttigieg seizes his moment

Buttigieg was the single standout performer on Tuesday. He took the fight to Warren, was prominent in the key early stages of the debate and made his case more broadly as a candidate able to connect with voters beyond the liberal base.

Buttigieg has always been an effective television performer, and he has showed startling fundraising strength.

He has, however, struggled to translate those assets into real momentum in the polls.

The 37-year-old mayor’s path into serious contention lies in the possibility that he could supplant Biden as the centrist standard-bearer against the progressive wing of the party, represented by Warren and Sanders.

He helped himself in a big way on Tuesday — and Biden’s weakness also played into his hands.


Harris misfires with Warren attack

Harris shone in the first Democratic debates in Miami in late June, but she has faded in the polls since then.

She enjoyed a good moment early on Tuesday when she turned a general discussion of health care to the topic of women’s reproductive rights — a winning move with the crowd in the hall, and presumably with a lot of Democratic voters.

Just as memorable — but for the wrong reasons, from Harris’s perspective — was a later exchange with Warren on the subject of President TrumpDonald John TrumpObama slams Trump in Miami: 'Florida Man wouldn't even do this stuff' Trump makes his case in North Carolina, Ohio and Wisconsin Pence's chief of staff tests positive for COVID-19 MORE’s Twitter account.

Harris pressed Warren on why she wouldn't support Harris’s push to have Trump banned from the social media platform. But Warren easily turned the attack around by saying that she was focused on removing Trump from the White House, not just from Twitter.

Harris persisted with the confrontation but the overall effect was to diminish herself rather than Warren, with the California senator seeming mean-spirited and somewhat petty.

It was a bad moment for a candidate who could ill afford one.
