The Trump administration built 52 miles of new primary border barriers — the first impediment people encounter if they’re trying to cross the southern border with Mexico, that can block access either for people on foot or for vehicles — where there were none before.

The administration built 458 total miles of primary and secondary border barriers, U.S. Customs and Border Protection data shows. The majority were replacements of smaller, dilapidated barriers.

The U.S.-Mexico border stretches for 2,000 miles across four states and a variety of terrain.

Christie was just asked about his position on a pathway to citizenship for undocumented immigrants. In a July poll by The New York Times/Siena College, 39 percent of likely Republican voters say that they supported a “comprehensive immigration reform bill that provides a pathway to citizenship for all undocumented immigrants” in the United States, while 57 percent opposed such a bill. Support was weakest among Trump supporters (29 percent) compared with DeSantis supporters (48 percent) and voters who say they will vote for another candidate (50 percent).

Lots of crosstalk in this debate so far, and Burgum continues to refuse to be left behind. He just talked over the moderators as they tried to move on to immigration in order to make a point about child care in North Dakota.

Inflation has cooled a lot compared to its highs last summer, at 3.7 percent more than last year as of August. Republican candidates are blaming government spending for inflation, but economists think the pandemic-era inflation was caused more by supply-chain problems caused by the pandemic and shifts in demand because people's needs changed.

Hello readers! I’m Jacob Rubashkin (not 1992 VP candidate James Stockdale), and I’m a reporter and analyst for Inside Elections, a small, nonpartisan newsletter that does in-depth coverage of House, Senate, gubernatorial and presidential races. You may have seen our “race ratings,” which we publish regularly to assess each party’s chance of winning every election around the country.

Tonight, I’ll be reporting for duty as a 538 contributor, as I’ve done for many debates, primaries, and general elections over the past two years. I’ll be providing live analysis on the events playing out on stage, and also thinking about how the course of the GOP presidential primary will affect the fight for Congress next year, when Republicans aim to win back full control of Washington, D.C. (The debate is taking place in California’s 26th District, which is Solid Democratic, but right next door is the highly competitive 27th District, where vulnerable GOP Rep. Mike Garcia might not appreciate having to run with Trump at the top of the ticket).
