Liberal Self-Identification Grows Among Democrats

Gallup reports:

The expansion in the percentage of liberals over the past five years has been most evident among adults who identify with the Democratic Party, rising from 39% in 2011 to 45% in 2015. Longer-term, the percentage of Democrats calling themselves liberal has climbed 16 percentage points from 29% in 2000, while the percentages who are "moderate" and "conservative" have both declined.

From 2000 to 2003, moderates were the largest ideological group among Democrats, followed by sizable proportions identifying as liberal and conservative. Since 2012, however, liberals have been the largest group, with a sizable moderate component and a significantly smaller conservative component.
