The New York Times and The Hill reported recent polling showing Democrats with an advantage among young voters ahead of the midterm elections, though the two surveys measure different things.
The New York Times reported that in the new Times/Siena poll, 70 percent of young voters identified as Democrats or leaned that way. The report described the figure as "a jump from just two years ago." The article was written by Claire Cain Miller and Rachel Buigas-Lopez.
The Hill reported, citing the latest Harvard Youth Poll, that Democrats lead Republicans by 37 points among young voters who say they will "definitely cast their ballots this fall." The article was written by Julia Mueller.
The Hill also reported that on a generic House ballot, Democrats were ahead 45 percent to 24 percent among voters aged 18-29, a 21-point advantage. The 21-point figure applies to voters aged 18-29 on the generic ballot, while the 37-point figure applies to young voters who say they will definitely vote, so the two numbers describe different groups.
The Times figure refers to partisan identification and leaning, while The Hill figures refer to a generic House ballot and to voters' certainty of voting. Neither summary states a result for the Times poll on vote preference. The summaries available for this report do not include sample sizes, margins of error, or field dates for either survey, so the results cannot be compared directly on those points. The Hill summary also breaks off mid-sentence while describing a further group of voters who are certain to vote.
