Riding a surge of enthusiasm in opposition to President Trump, more Democrats turned out in the primaries for House elections than Republicans this year — the first time that has happened since 2008.

Why it matters: 2008 was the last time Democrats won a majority in the House. They lost it in 2010, when Republican primary turnout skyrocketed and Democratic turnout plummeted — the reverse of what's happening now.

What's next: David Brady, electoral politics expert and senior fellow at the Hoover Institution, predicts around a 7% Democratic turnout advantage in November driven by women, and particularly Independent women.

  • Meantime, Republicans are trying to energize their voters, since Republican National Committee polling suggests a majority of Trump voters don't believe Democrats could win the House, per Axios' Jonathan Swan.

This is one of the bigger signs of trouble for President Trump that we've seen in a poll: Of the final debate's seven topics, Joe Biden won or tied on all seven when viewers in a massive Axios-SurveyMonkey sample were asked who they trusted more to handle the issue.

Why it matters: In a time of unprecedented colliding crises for the nation, the polling considered Biden to be vastly more competent.

Entomologists in Washington state on Thursday discovered the first Asian giant hornet nest in the U.S.

Why it matters: You may know this insect species by its nom de guerre: "the murder hornet." While the threat they pose to humans has been overstated, the invading hornets could decimate local honeybee populations if they establish themselves.
