Our thinking this week, amid all the carnage and grief and finger-pointing, has been in part on Beto O’Rourke, the presidential candidate from El Paso, where 22 people were killed last Saturday. Our sympathy is devoted to the dead and their families, of course — but Beto has been on our minds, too.

We keep coming back to a moment last Sunday when, for a few seconds, all the pretenses that are part of running for president in our age of constant exposure were peeled back, if only briefly.

There are times, it seems, in most presidential campaigns when the facades get stripped away like so many layers of paint. What’s left is a human moment, usually fleeting, and not always flattering. But real — and often more telling than a season of advertisements.

Hillary Clinton tearing up in New Hampshire in the winter of 2008. Ronald Reagan’s humor during a 1984 debate when, asked if he wasn’t too old to serve four more years, he replied that he had no plans to use his opponent’s youth and inexperience against him. Even Walter Mondale laughed with the audience.

Something like that happened last Sunday with O’Rourke, when a news reporter asked O’Rourke whether he felt there was anything President Trump could do to cool the atmosphere of hate toward immigrants.

“Um, what do you think?” O’Rourke responded bluntly. “You know the s*** he’s been saying. He’s been calling Mexican immigrants rapists and criminals. I don’t know. … Like, members of the press -- what the f***? It’s these questions that you know the answers to …”

Is that language presidential? Not normally. It certainly isn’t the normal fare for an editorial page in the Sunday paper, either, with or without the asterisks. But it struck us as so unscripted, so unexpected that its offense was somehow washed away.

The Atlantic called it the “art of giving a damn” in a piece last week about anger washing over the Democratic candidates.

O’Rourke has had these moments before. Last year, he was asked if he supported Colin Kaepernick, the NFL quarterback whose protests by kneeling during the national anthem sparked a nationwide conversation. Instead of giving a safe, wishy-washy answer, he gave a heartfelt yes: “I can think of nothing more American than to peacefully stand up or take a knee for your rights, any time, anywhere, in any place.”

It went viral, the way his answer last Sunday did. We aren’t used to seeing candidates act like real people.

Frankly, it’s made us wish O’Rourke would shift gears, and rather than unpause his presidential campaign, we’d like to see him take a new direction.

So Beto, if you’re listening: Come home. Drop out of the race for president and come back to Texas to run for senator. The chances of winning the race you’re in now are vanishingly small. And Texas needs you.

Two years ago, you ran an inspiring race against Sen. Ted Cruz. Sure, you lost. No shame in that. Texas hasn’t elected a Democrat to a statewide office since 1994. You chipped away at a wall that wasn’t quite ready to come down. You showed it’s possible.

For too long, Texas officials have had only to consider how far to the right they must go to stay in office. No one is asking whether there might be a good idea or two on the Democratic side of things. We need you, Beto, because Texas badly needs that other view of the world, those differing opinions. You’ve brought us closer to having real, competing parties than any other candidate has, and than any candidate on our radar could.

Would you beat John Cornyn, who is seeking his fourth term? It wouldn’t be easy. You’d have to fight for it, and do better than you did against Cruz. But a lot has changed since 2018 — you had a lot to do with that — and Trump is no longer rock-solid in Texas. Neither are the Republicans who support him.

Imagine the effect you could have on our state. Ideas get sharper when they’re challenged, when points of view clash. We think Texas will get smarter, and its politics more sophisticated, if campaigns here were a true test of ideas, not one-sided races set to autopilot.

So please, Beto, after you’ve taken some time to mourn the dead in El Paso, consider whether now is a good time to leave one race and join another. Texas needs you back home.
