NPR Correspondents Explain How to Read Midterm Polls and Watch Races

Central Indiana readers face a familiar question as they head to the polls on Tuesday: can they trust the numbers? Domenico Montanaro, NPR's senior political editor and correspondent, addressed this directly in a Q&A with listeners. He noted that while national polls have accurately tracked the horse race, state-level surveys have suffered from quality control issues.

Montanaro explained that a poll with a margin of error of plus or minus three or four percentage points actually represents a range of six to eight points. In close elections, this wide band makes precise predictions difficult. He attributed the rise of low-quality or fake state polls to the financial decline of local journalism. Local newspapers and television stations often lack the funds to pay for rigorous, frequent polling, leaving a gap that national outlets try to fill.

The reporters also discussed the appeal of covering midterm elections compared to presidential cycles. Sam Gringlas, an NPR congressional reporter, described the work as more intimate. He recounted accompanying candidates to an antique shop, a farmer's market, a UAW picnic, a family farm, and a smokejumper-themed brewery. These smaller venues allow for closer observation of how candidates interact with voters, a dynamic less visible in the stadium-sized rallies of presidential campaigns.

Tamara Keith, another senior political correspondent, highlighted the drama of Nevada's 2nd Congressional District. She described the race as messy, involving a Republican nominee who moved to the district specifically to run for Congress and a Democrat who is a former Miss Nevada turned state legislator. The retiring Republican congressman in that district recently announced he voted for a Libertarian instead of his own party's nominee.

Keith and Montanaro both flagged specific down-ballot races that may not dominate national headlines but offer clear signals for the day's outcomes. Keith pointed to South Florida and South Texas, where Latino voters act as a swing group. Montanaro suggested watching the Nevada governor's race, where incumbent Republican Gov. Joe Lombardo faces Attorney General Aaron Ford. The race features debates over crime and unemployment, as well as Ford's past legal issues.

If Democrats take one or both houses of Congress, Montanaro said, the primary effect will be increased investigations and oversight of the executive branch. He noted that legislative progress often stalls during periods of split power. Historically, only two times since World War II has the president's party gained seats in a midterm, occurring in 1998 and 2002. These historical benchmarks provide context for Tuesday's results.
