Democratic presidential candidate Andrew Yang broke down Saturday at a forum in Des Moines, Iowa, hosted by Everytown for Gun Safety, as he discussed gun violence with a woman whose 4-year-old daughter was killed by a stray bullet.

Details: The woman said the girl's twin saw the incident. "She died 2 days later,” the woman said. "As president, how would you address unintentional shootings by children?" After composing himself, Yang outlined his policy for personalized guns, which include safety features to prevent unauthorized use. "One of my proposals is to actually help gun owners upgrade their guns to personalized guns free of charge," he said.

The big picture: A June Johns Hopkins Bloomberg School of Public Health study of 1,444 gun owners surveyed found 4 in 5 support the sale of both traditional and personalized guns through licensed dealers. Only 18 percent of gun owners reported being likely to buy a personalized gun for themselves when considering the additional costs.

  • Yang told the forum, "If we can convince Americans that personalized guns are a good idea then again, if the child gets ahold of the gun, then they can't do anything with it. Then it just becomes a very heavy, expensive prop."

The art and business of political polling

The election is just eight days away, and it’s not just the candidates whose futures are on the line. Political pollsters, four years after wrongly predicting a Hillary Clinton presidency, are viewing it as their own judgment day.

Axios Re:Cap digs into the polls, and what pollsters have changed since 2016, with former FiveThirtyEight writer and current CNN politics analyst Harry Enten.

Twitter launches warnings on election misinformation and delays

Twitter will start pinning notices to the top of all U.S. Twitter users’ timelines warning that results in next week’s election may be delayed and that they may encounter misinformation on mail-in voting.

Why it matters: Delayed election results are expected across many states that are handling unprecedented amounts of absentee and mailed ballots, which President Trump has baselessly called "very dangerous" and "corrupt."

Water on the Moon might be more easily accessible than previously thought, opening up new possible avenues for future human exploration, according to a new study.

Why it matters: NASA is aiming to send people back to the Moon as part of its Artemis program by 2024, with plans to eventually create a sustainable presence on the lunar surface. That sustainability relies on mining the moon for its resources, like water.
