My guess (based on no hard facts, bust purely speculation): This statistic is for the age group of 18-29 year old. Young people tend to be more liberal and grow more conservative as they age.
There might also be a political or economic component, but i think age is the primary reason why these graphs mostly show a liberal bias for the samples.
