Marist

Marist College's Institute for Public Opinion (MIPO), founded in 1978 and based in Poughkeepsie, New York, is one of the United States' most frequently cited academic polling organisations. Its long-standing partnerships with NPR and PBS NewsHour give its results wide national reach. A Marist poll fielded 8-11 June 2026 and published on 18-20 June found Trump's economic approval at a record-low 33%, with 22% of Republicans disapproving of his economic handling, a data point that shaped mainstream analysis of the midterm environment .

The institute operates as an independent, non-partisan unit within Marist College. It conducts telephone and online surveys, publishes toplines and crosstabs publicly, and is rated as a high-quality pollster by the American Association for Public Opinion Research. Its generic-ballot readings have historically clustered in the institutional centre of the polling distribution, making it a key reference point in electoral aggregators such as Nate Silver's Silver Bulletin.

For the 2026 midterms, Marist's economy-approval series is particularly significant: it extends back to 2019, providing one of the longer continuous tracking records on Republican presidential approval. A sustained low-33% economic rating, if confirmed by other institutional pollsters, would historically correlate with meaningful seat losses for the president's party in the House.
