Welcome aboard the Acela, listeners. Today on the FiveThirtyEight Politics podcast, we are taking a break from the campaign trail and heading to Washington, D.C., where there’s quite a lot going on. House Speaker Kevin McCarthy announced last week that Republicans are opening an impeachment inquiry into President Biden. There are also just 12 days until a possible government shutdown. And some Republicans are threatening McCarthy's speakership. Politics reporter Leah Askarinam and POLITICO Playbook co-author and ABC News contributor Rachael Bade join Galen Druke to discuss. They also play a round of "Quiz of the Union," where they try to put this year's higher-than-usual number of strikes in the context of public opinion. Learn more about your ad choices.

Among the most politically tuned-in, last week saw the kind of hand-wringing and accusations of bias surrounding the polls that you’d usually expect from the final two months of a campaign, not the final year and two months of a campaign. The focus was largely on general election polls: Whether a Wall Street Journal poll showing former President Donald Trump and President Biden tied is to be trusted. What to make of a CNN poll showing Nikki Haley as the only Republican candidate with a lead over Biden that falls outside the margin of error. How to understand data from the New York Times suggesting that Biden is losing support among voters of color. In this installment of the podcast, Galen speaks with Carlos Odio of Equis Research and Terrance Woodbury of HIT Strategies to parse through which recent data is actually worth paying attention to and which is sound and fury.

Now that we are on the other side of Labor Day and summer is subsiding, this is — as tradition goes — when focus on political campaigns really begins to heat up. The off-year elections this November will get some attention, but the main attraction is still the 2024 Republican presidential primary. In this installment of the podcast, we ask a question we will undoubtedly return to in the four months until the Iowa caucuses: Is Donald Trump’s nomination inevitable? And if not inevitable, how can we place the likelihood he wins the GOP primary in historical context? We also have partial results from two special primary elections and we debate “good or bad use of polling” for a classic and controversial topic: internal polls. Learn more about your ad choices.

This is a special end-of-meteorological-summer installment of the FiveThirtyEight Politics podcast. Galen Druke speaks with pollsters Kristen Soltis Anderson and David Byler in an episode made entirely of "good or bad use of polling" examples. They consider why GOP primary candidate Vivek Ramaswamy polls differently depending on survey methodology, what we can learn from post-debate polling, whether Nikki Haley used polling well in her debate performance and more.
