Not quite. Polls underestimated Democratic support in 2018, 2019's special elections, 2021's special elections, the 2022 midterms, and last year's elections. It's been remarkably consistent how far off they've been.
Do I prefer that to the other way around, as happened in 2016? Sure. But they've clearly over-corrected, and are having significant trouble getting back on track due to the difficulty of polling young people.
