In Kentucky, this past Tuesday was Primary Day. The day every registered voter, in the appropriate party, could go to the polls and say who we want to run to represent our party in the General Election.
While political parties, as such, need to be abolished, and voting is borked, that every state holds its Primary on a different day is wildly unhelpful.
Because they are not on the same day, you often are presented with candidates who are neither your first nor second, or perhaps even your third choice.
Since the General Election is fixed nationally to happen on the first Tuesday after the first Monday in November, state-by-state Primary Election days should also be fixed to happen simultaneously across the country.
