The JWS doctrine of not associating or being involved in governmental institutions is a mistranslation of Jesus's words when he said my kingdom is no part of this world,
There was no instruction for his followers to not be themselves.
The other fact to consider is there are many biblical figures in the bible who were or had political governmental positions of god's chosen ones/people within the Hebrew civilization.
Just to point out a fact, the government of the time of Christ was the established Roman government which was for a long time against Christianity and that followed through until emperor Constantine overruled that position and embraced Christianity to become the official religion of the government/empire. (313 AD)
