I am a proud, "unaffiliated" voter, and vote for the candidates who express the best support for constitutional governance, even if they are supporters of the Standing at the Back Dressed Stupidly and Looking Stupid Party (Blackadder reference). As a former supporter and all-around leader of the Democratic Party, I witnessed firsthand how many of its leaders and their supporters broke laws, bent rules and generally cheated. I suspect greatly, though haven't witnessed, that the same is true with the Republican Party, and its leaders and supporters. I refuse to vote for the better of two evils; doing so only guarantees continued evil. I vote "no" on all judicial-retention elections because they never have opponents (that is technically a plebiscite not an election). I vote "no" on referendums and initiatives if they would cost tax dollars. I support a devolution of centralized governmental authority. In today's jargon, I would be called a libertarian, but I prefer calling myself a Jeffersonian constitutionalist.
As a former county-elections staffer, I learned how to vote legally in certain ways that confuse and unhinge the political parties and their candidates.
