There are a lot of reasons for Democrats to be cheery on Wednesday, but the outcome of the midterm Senate races is not one of them. With three key races (Arizona, Florida, and Montana) still too close to call, and the Mississippi race going to a runoff, Democrats are looking at a potential 45-55 make-up in Republicans' favor in 2019. "It's not the only important takeaway, but one important takeaway from last night is that it's going to be basically impossible for Democrats to have a governing coalition if they beat Trump in 2020," explained Vox's Dylan Matthews.

The math could look like this: In 2020, Democrats would need to hold all of their current Senate seats — including Alabama — plus flip six held by Republicans, including in all likelihood Arizona and Georgia, as well as places like Iowa, Colorado, Maine, and North Carolina. (As David Faris explains for The Week, "Democrats may very well be underdogs everywhere but Colorado.")

To be fair, the 2018 map never looked any good for Democrats. The party had to defend 10 seats in states President Trump won in 2016, and had hinged chamber-flipping hopes on red states like Tennessee and Texas. The math will be the opposite in 2020 — Republicans will be on the defensive, with 21 Senate seats up compared to 12 being defended by Democrats. But it is still a long, uphill battle to retaking the Senate after Tuesday night. Jeva Lange

Hablas español? Former Texas Rep. Beto O'Rourke and New Jersey Sen. Cory Booker do, and they put it to full use on Wednesday night, with O'Rourke even receiving a question from Telemundo anchor and debate moderator José Diaz-Balart in Spanish.

At least a few of Thursday night's crop of Democrats were watching and taking note — and, presumably, hastily downloading Duolingo.

One Thursday candidate likely wasn't sweating it, though: South Bend, Indiana, Mayor Pete Buttigieg, who speaks Spanish in addition to Norwegian, French, Italian, Maltese, Arabic, and Dari. Jeva Lange

President Trump is not entertained.

As 2020 Democrats debated on Wednesday night, Trump, who had previously promised to live-tweet the debates, stayed uncharacteristically silent. That's apparently because, as he tweeted 35 minutes into the debates, it was "BORING!"

Trump's one-word tweet came as Democrats onstage discussed the stunning photo of a migrant father and daughter who died while crossing the Rio Grande. Beto O'Rourke, who broke into Spanish during the discussion, tweeted earlier that Trump is "responsible" for their deaths. The photo came as a visceral reminder of the ongoing humanitarian crisis at the U.S.-Mexico border. Kathryn Krawczyk

Sen. Elizabeth Warren (D-Mass.) made her stance on health care policy very clear during Wednesday's Democratic primary debate.

When the 10 candidates on stage in Miami were asked whether they would abolish private, for-profit health insurance for a government-run plan, only two raised their hands: Warren and New York City Mayor Bill de Blasio.

After Sen. Amy Klobuchar (D-Minn.) gave a brief defense for an incremental approach and retaining a public option, Warren expressed her support for a government-run plan. The senator, who has been surging in recent weeks, said health care is a human right and declared that she stands with her old friend Sen. Bernie Sanders (I-Vt.) in support of Medicare-for-All. Sanders' supporters in the past have questioned Warren's commitment to the idea. Tim O'Donnell

Julián Castro has a simple pledge for closing the gender pay gap.

Castro, who served as Housing and Urban Development Secretary under former President Barack Obama, was asked at Wednesday's Democratic debate how he would address the gender pay gap. He immediately brought up how his single mother raised him and his twin brother, Rep. Joaquin Castro (D-Texas), and then pledged to "pass the Equal Rights Amendment, finally."

The Equal Rights Amendment to the Constitution was proposed nearly a century ago. It passed the U.S. Senate in 1972 and has slowly made inroads in state legislatures, but has stalled ever since. Kathryn Krawczyk

It took former Texas Rep. Beto O'Rourke exactly nine seconds to start speaking in Spanish at the Democratic debate on Wednesday night. After being asked if he would support a marginal tax rate of 70 percent on the highest earners making more than $10 million a year, O'Rourke answered instead: "This economy has got to work for everyone, and right now we know that it isn't, and it's going to take all of us coming together to make sure that it does."

He then switched to speaking Spanish, which bilingual viewers noted was a dodge as the former congressman didn't actually answer the question in either language:

Still, O'Rourke managed to impress some people with his bold decision:

New Jersey Sen. Cory Booker — who also speaks Spanish — looked particularly impressed and surprised:

Several of the 2020 Democrats are multilingual. In addition to O'Rourke and Booker, Julián Castro and Pete Buttigieg have also given interviews in full or in part in Spanish, Politico reports. Jeva Lange

So far, it seems, the Democratic primary candidates who are slated to take the debate stage on Thursday in Miami are perfectly content to allow their Wednesday counterparts their moment in the spotlight.

Former Vice President Joe Biden reportedly won't even be in Miami until Thursday, though he has been keeping busy — he's reportedly still in Wilmington cooped up in a hotel for "debate camp." The front-runner, NBC News reports, is in the midst of "marathon" practice sessions and will watch Wednesday's event from Delaware.

Despite the intensity of Biden's preparation, though, he and his team have downplayed Thursday's debate. "It's a little bit of an exaggeration calling it a debate," Biden told reporters earlier this month. "I mean there's not much time."

Sen. Bernie Sanders (I-Vt.) is already in Miami, where he's been greeted by some cheering crowds, but he's seemingly keeping his thoughts to himself.

Other notable candidates who have to wait until Thursday, like South Bend Mayor Pete Buttigieg (D) and Sen. Kamala Harris (D-Calif.), are also reportedly in Miami already, but they too have kept a low profile on Wednesday. Tim O'Donnell
