I guess this result doesn't seem surprising to me? A majority of the general public can't even identify how long Senate terms are (https://www.pewresearch.org/short-reads/2023/11/07/what-amer...); they simply don't have the required knowledge to meaningfully influence politics without mediation through interest groups. (Anecdotally, it’s a truism in political circles that you will drive yourself insane trying to understand the median voter’s theories of politics.)
