Every contest should be closed. If you can't even check a f[inks]ing box then you shouldn't have a say in the party's nominee.
Oddly enough, that's maybe not the problem. More of my friends who had checked the box have as of yesterday found out they couldn't vote in a primary because somewhere in the system it had become unchecked. Keeping closed primaries prevents folks who consider themselves Democrats, who vote Democrat, and who registered as Democrats from participating. What more, there are lots of independents who are more reliable Democratic voters than some people who are registered as Democrats. Having open primaries also encourages people to get in the habit of voting fro Democrats. If you do it in the primary, you're very likely to do it in the general. Can't do it in the primary, why even show up to vote in the general? This party doesn't seem to care what you think.
Its absurd to exclude people due to clerical error (or worse) and its absurd to cut out people who we need in our coalition from having a say in it. Fine, force them to reregister as Democrats, but allow same day registration in that case. But if you don't have it, let it be open. Grow the party and stop thinking of independents as the enemy.
