On Tuesday — National Voter Registration Day — the Auraria campus in downtown Denver was practically barren, so uninhabited that a shout of “Are you registered to vote?” easily cleared the plexiglass shield in front of New Era Colorado’s tent and echoed down the walkways. Gone were pre-pandemic features like circus performers and walls lined with fresh goodies for the taking, temptations that in years past lured hordes of college students headed to class to the youth civic engagement group’s voter-registration booths. Instead, a select few New Era employees — all masked — hit the university pavement to help young people register to vote, at a distance, and distribute their notoriously profane voter advocacy merchandise along with coffee drinks, chips, extra face coverings and hand sanitizer. “There are no longer huge masses of young people scurrying across the campus,” said Nicole Hensel, executive director of New Era Colorado.
