A Republican House takeover is "no longer a foregone conclusion," according to a dispatch today by The Cook Political Report with Amy Walter.

• Why it matters: The fact that there's now a narrow path for a Democratic majority is a sea change from expectations just a couple of months ago.

What's happening: Concern over protecting abortion rights is igniting Democratic voter engagement. And lower gas prices are easing the party's deficit with independents, Axios' Josh Kraushaar writes.

🚨 Driving the news: The publication's U.S. House editor, Dave Wasserman, today moved the ratings of five House seats — all in Democrats' direction.

• The Alaska House seat that Democrat Mary Peltola won in a special election over Trump-backed Republican Sarah Palin is now "toss-up" for November.
• Virginia Rep. Abigail Spanberger, representing a bellwether suburban district that backed President Biden by 6 points, is now favored to win re-election against Republican Yesli Vega.

📊 A new Wall Street Journal poll, conducted by Trump pollster Tony Fabrizio and Biden pollster John Anzalone, shows clear Democratic momentum over the summer.

Twitter is testing a tweet "edit button," Axios' Ina Fried reports.

• Why it matters: The feature has topped customer requests for years. The tricky part is allowing edits without opening the door to spam and misinformation.

🛠️ How it works: The edit feature lets users change tweets "a few times" within 30 minutes of posting.

• An edited tweet will appear with an icon, time stamp and label. Tapping the icon will pull up past versions.
• If someone retweets a post that is later edited, the version that was shared will remain visible.

🔮 What's next: Twitter's edit feature will expand to "a select group of people including Twitter Blue subscribers in the coming weeks."
