A lot of politicians seem to think reddit as a strong liberal community that would be favorable to all the ideals of the Democratic Party but I think it's more libertarian than liberal most of the users are males between 18-29 so the ideal group that appeals to libertarianism. Some staffer probably told him this was a way to reach out to young liberal millennials.
Yeah, reddit is a very right-wing/libertarian website.
Reddit is
very politically diverse but on balance it's probably mildly left-leaning.
