Politically Active
At its best it means interested in politics and government; trying to make a changes in public policy, laws or the government working to get an official elected, or lobbying to have legislation passed, collecting petition signatures. It can also mean a person trying to change things for their own benefit, to gain status or power in the workplace. It can also mean someone who is a nuisance, constantly wanting to change things and who interferes in matters that are none of their concern. At its worst it means a total fuckwit like Russell Brand a self-styled activist for whom politically active means espousing views that the majority of people find repugnant or ridiculous.
Some people are politically active because they have nothing else in their lives.
Politically active
Someone who's involved in politics through financial or through an office. Someone who doesn't even vote isn't politically active.
Apathetic is the opposite of politically active, so calling somebody who doesn't vote politically active and apathetic is like calling a house cheap and expensive.
