Living in a deep red state, it’s the only chance I have to cast a vote that matters. Not just the presidency, but most of our state and local politicians are decided in the Republican primary. Half the positions I’m talking about literally run unopposed in the general election. So I’m going to keep voting for the lesser evil and doing what I can where I live.
Read my comments further down. Your party affiliation is whatever you decide it is. There are plenty of reasons to register, vote, or support candidates contrary to party affiliation. That doesn’t make you ‘not party X’ unless you decide you are no longer supporting party X. It seems pretty simple to me.
