Ham radio enthusiasts are a constituency political pundits don't pay enough attention to at their own peril.
Hobbyist Rocketry is kind of hard to gauge.
I recently came back from a hobbyist rocketry competion in California which also has a similar divide. Most of the teams competing in it are university students who lean heavily democrat and liberal(a transwoman runs one of the most active hobbyist sites) but the elder organizers are very conservative.
At the end when we are doing some analysis on our rocket one of the organizers mentioned to me "one of our political parties wants men to be able to use woman toilets" offhandidly after a team member complained about crowding of the woman's restrooms.
