Megan Brennan at Gallup:
Republicans have always been most likely to identify as conservative, but in 2024, 77% described themselves as such, marking a new high by two percentage points and a four-point increase from 2023. This includes 24% of Republicans who said they were very conservative, which is also a new high by one point.
Another 18% of Republicans said they were political moderates, which is the first time the reading -- which was as high as the low 30s from 1998 to 2002 -- has fallen below 20%. Just 4% of Republicans said they were politically liberal, consistent with prior readings.
