When it comes to trek fans and political affiliation here is what I have experienced / discovered.
Star Trek Original Series = Either hippies or Libertarians
Star Trek The Next Generation = Soft Socialists / Liberals
Star Trek Deep Space Nine = Hard Core Conservatives
Star Trek Voyager = Hard Core Liberal Control Freaks
Star Trek Enterprise = No One Admits they like it...
Just the trend, there are always exceptions.
"Star Trek Enterprise = No One Admits they like it..."
I really enjoyed Star Trek: Enterprise. Much more than I ever did "The Next Generation" or "Voyager". The development of the show, along with the obvious first-generation equipment that was being tested on the Enterprise, as well as the alternate reality versions of it, were quite original and, to me, very enjoyable.
