(GALLUP) — PRINCETON, N.J. -- Many more Americans have considered themselves politically conservative than liberal since the early 1990s. That remained the case in 2016, when an average of 36% of U.S. adults throughout the year identified themselves as conservative and 25% as liberal. Yet that 11-percentage-point margin is half of what it was at its peak in 1996 and is down from 14 points only two years ago.
Since Gallup began routinely measuring Americans' political ideology in 1992, conservative identification has varied between 36% and 40%. At the same time, there has been a clear increase in the percentage identifying as politically liberal, from 17% to 25%. This has been accompanied by a corresponding decrease in the percentage identifying as "moderate," from 43% to 34%.
