Snowflake ABSOLUTELY can describe Republicans and conservatives.  White, pissed off conservatives sitting on their asses in Pennsylvania, Wisconsin and Michigan, whining about the government bringing them jobs instead of getting off their asses and either moving where there ARE jobs, or re-educating themselves to get current jobs.  Those are "snowflakes" who think they're somehow special and the government they love to hate owes them something.  I've got MANY more examples if you're interested.
