From Pew:
Seven months into President Donald Trump’s administration, nearly half of all Democratic and Democratic-leaning registered voters describe their political views as liberal. The share of Democrats who describe themselves this way has steadily risen and is now 20 percentage points higher than in 2000.
Through the first half of 2017, more Democratic voters identify as liberal (48%) than as moderate (36%) or conservative (15%), based on an average of Pew Research Center surveys. In 2008, 41% of Democratic voters called themselves moderate, while 33% said they were liberal and 23% said they were conservative. And in 2000, Democratic voters who called their views moderate outnumbered liberals by 44% to 28%, while 23% said they were conservative.
