Clean shaven would be very Republican demographic. Think about the military or business environments where they enforce strict facial hair policies.
It's still not entirely clear to this day which candidate active duty military voted for, but there is some evidence suggesting they voted for Biden overall.
Do you have links? I imagine active duty military would be a Republican-leaning group overall because Republicans are generally more supportive of increased military spending. I imagine that Trump's opposition to mail-in ballots might have hurt Trump's performance dramatically with this group of voters, though.
