WASHINGTON — How much has social media ruined American politics and political journalism?

Well, check out these numbers from the latest NBC News/Wall Street Journal poll:

57 percent of Americans say social media does more to divide the country than unite it;

61 percent say social media does more to spread unfair attacks and rumors against public figures and corporations instead of holding them accountable;

55 percent say it does more to spread lies and falsehoods rather than news and information;

and a whopping 82 percent of Americans say social media does more to waste time – instead of using it well.

Those numbers come, of course, as nearly seven-in-10 Americans — 69 percent — say they use social media at least once a day.

There are many culprits for what ails American politics right now. The urban-versus-rural divide. Gerrymandering. Polarized media. Partisan cable TV.

But when you look at these poll numbers, you have to add social media to the list.

By the way, when was the last time the two major political parties both had relatively popular presidential nominees? It was back in 2008 — hello, Barack Obama and John McCain — when Twitter and Facebook were in their infancy.

We aren’t saying there’s a direct correlation, but it’s something to chew on.

Social media erases nuance and the ability to pause – you never stop.

And for American politics to succeed, you need some nuance, as well as time to reflect.

Border troubles for Republicans

President Trump today heads to the California-Mexico border – a day after backing off his threat of closing the southern border.

Trump’s shutting-down-the-border threat didn’t please Republicans from border states.

Here what Sen. John Cornyn, R-Texas, who’s up for re-election next year, told reporters this week: "I told Trump] that I understand his frustration, but I also believe shutting down the border would have a lot of unintended consequences.”

Remember, Republicans got CREAMED in border states in 2018 – they lost seven House seats in California; they lost a Senate and House seat in Arizona; they got swept in New Mexico; and Democrats saw their best performance in Texas in 28 years.

And it raises the question: Are Trump’s border games good for border-state Republicans?

2020 Vision: Howard Schultz pulls a Clint Eastwood

Here was possible independent presidential candidate talking about immigration in his town hall on Fox News last night:

“[Immigration] cannot be solved currently because of the ideology of both parties… I would bring the people into the room. I would say, 'You cannot come in here with ideology or ego.’ What I want to do is put an empty chair in the room, and that chair represents the American people.”

More Schultz: “And we're not going to leave the room until we solve the problem for the American people. The problem that we have with both parties – the American people are not in the room.”

Data Download: The number of the day is … 62 percent

Sixty-two percent.

That's the share of Florida voters who approve of Republican Gov. Ron DeSantis' job performance, according to a Mason-Dixon poll of the state.

DeSantis is even above 50 percent approval in blue-leaning southeastern Florida, home to the Democratic stronghold of Miami.

Almost six-in-10 independents approve of his job, along with 41 percent of Democrats.

Other pollsters have seen a similar trend too—Quinnipiac University found DeSantis with a 59 percent favorable rating in its poll last month. That's the highest gubernatorial approval rating in Florida over the past decade of its polling, Quinnipiac said.

These numbers are especially notable considering Florida's partisan split, not to mention the fact that DeSantis is just months past a divisive gubernatorial race where Democrats pulled no punches against him.
