Rules 0
I was at a political function this past weekend. One of my acquaintances was kvetching about complaints from Sanders supporters about some primaries, specifically, complaints that they “had not been allowed to vote,” when, in fact, the issue was that they had not ensured that they were properly registered to vote.
Virginia is an open primary state, but many states have “closed primaries,” which means that, if you wish to vote in a party primary, you must be a registered to vote as a member of that party. If you wish to vote in the Democratic primary, you must be registered as a Democrat; in the Republican primary, registered as a Republican; in the Green Party primary, registered as a Green, and so on. Delaware, where I used to live, was a “closed primary” state.
This is nothing new.
Sanders supporters who were not registered as Democrats were not allowed to vote in Democratic primaries in closed primary states, and, frankly, that was their own damn fault.
“How simple would it have been,” fumed my acquaintance, “for Bernie to tell his supporters to register to vote.”
