How do Rotarians vote?

[Blow by blow, the passion dies]

We might never know.

[Progressive Pessimist]

My Uncle was the head of the local Rotary society and he is a staunch Democrat, federally at least, though has voted Republican for local office before.

While he tends to be a bit more swingy for local elections, I think that's only because his wife (my aunt, obviously) is good friends with their neighbor who is one of the most prominent local GOP members in our borough.

[Skill and Chance]

Generally speaking fraternal/secret societies = Republican, but less dramatically so for the unisex ones like Rotary.  Small business owners and investors tend to be very overrepresented in these groups.  However, they are also very old school, so it's possible that specifically anti-Trump Republicans are also overrepresented.

They vote boisterously.
