The Note: Trump faces defining choice on guns

The Democratic candidates are bringing the passion.

The Take with Rick Klein

The Democratic candidates are bringing the passion.

Trump faces what may be a defining choice in the days to come. He could confront his own party and some of its most powerful backers on a stubborn issue that has provoked raw emotions, or backtrack as he has after previous episodes of awful violence.

If he chooses the former, Trump might even clear a bar that would-be opponents have set for him.

"It's a matter of leadership, presidential leadership," Sen. Cory Booker, D-N.J., said on ABC News' "This Week" Sunday. "I hear a lot of the pundits say that if Donald Trump actually took responsibility for this moment, and stepped forward and said this is something we should do, that it would move Mitch McConnell and a lot of other folks."

There are lots of reasons to think nothing will change on guns: The power of the NRA; Trump's propensity to serve his conservative base; the long month before the Senate reconvenes, including Bedminster, New Jersey, time for the president this week; the mistrust of and disdain for Trump that has extended to 2020 candidates flatly calling him a "white supremacist."

But Trump has dictated ideology and action to the Republican Party in the past. If something does happen on the legislative front on guns, it will almost certainly be because the president wanted it to.

The RUNDOWN with Alisa Wiersema

Over the course of four days, 21 candidates swarmed the Iowa State Fair, kicking off the unofficial start of the 2020 campaign season, but amid the fried food, farm animals, press gaggles and glad-handing there was a notable absence. Faced with a test of presidential-level resolve amid tragedy, former Rep. Beto O'Rourke sat out his scheduled Iowa events in favor of spending more time in his hometown of El Paso, Texas, as the community mourned last week's mass shooting.

As his 2020 rivals made their cases for gun reform from the famed Iowa State Fair Soapbox, O'Rourke joined mourning students at an El Paso high school assembly to honor the lives lost, and later, met with family members of some of the victims.

Ahead of Friday's Wing Ding Dinner -- Iowa's version of political speed dating -- Democrats embraced one another during a moment of silence to honor the victims of last week's shootings, before moving on to making their pitches to Iowa voters. In stark contrast, O'Rourke's appearance came in the form of a pre-recorded video in which he urged for unity, while apologizing for missing the event.

On the ground in El Paso, O'Rourke expressed gratitude to his Democrat rivals, saying he's "so grateful to all of them who joined in a moment of silence [Friday] for the victims in Dayton and El Paso, and gun violence all over this country." He added that he is "grateful for their leadership on these issues."

In the fallout of these mass shootings, O'Rourke's own leadership is being put under the microscope. Most voters ABC News spoke with in Iowa said they understood O'Rourke's decision to sit out the state fair events, but still wished they had an opportunity to hear from him. Many voters at the fairgrounds were visibly disappointed to see O'Rourke's name crossed off the soapbox lineup sign, and some even made the jump to question whether it meant his campaign was coming to an end.

Now, as candidates aim to keep up the momentum for gun reform following last week's tragedies, O'Rourke is likely to see another test -- whether he will be able to carve out a unique place in the ongoing debate that hit so close to home.

The TIP with Christopher Donato

Democratic presidential candidate Andrew Yang caught people's attention this weekend. It started on Thursday when Yang secured his fourth poll of at least 2%, a threshold that appears to have qualified him for the September and October debates. At the Iowa State Fair on Friday, the "Yang gang" -- kids wearing math hats -- surrounded him as he walked around the fair, answering fair-goers' questions and consuming a turkey leg and lemonade.

Then on Saturday, Yang had an emotional moment on stage while answering questions at the Everytown Gun Sense forum in Des Moines. He spent a few minutes discussing his ideas to address gun violence before a woman talked about losing her 4-year-old daughter to a stray bullet, and explained that the girl's twin brother witnessed it happen. He walked down to hug her and returned to the stage to speak, but covered his face and started crying. "I have a 6 and 3-year-old boy, imagining … I was imagining it was one of them that got shot and the other saw it. I'm so sorry," Yang said after he regained his composure.

With reporters, he reflected on his emotional moment and the "delicious" turkey leg he at the Iowa State Fair before turning his attention to Trump and shifting his tone. Yang said that he didn't eat too much "crap" at the fair "because I need to stay in presidential form … no one wants a president who doesn't seem like they can run a mile. … I don't think Donald Trump could run a mile ... what does he weigh? Like 280? I say he like passes out at like the quarter-mile mark."

Yang said that there isn't much Trump would be able to beat him at other than "being a slob" and said that Trump could prevent a hot air balloon from rising "because he is so fat." Yang wrapped up by offering to challenge the president "in about any physical or intellectual feat because you're a terrible president and America would love to see you pass out trying to run a mile."
