Alaska did not have open primaries before. Except if you mean way before. In which case, if they ran this election like the elections back then, then Pelota and Palin would be running in the general as they were the top two vote recipients.

Now I'm not sure if Alaska was semi-closed, but that's not moving the needle as hard as you want it to. Because if you're already registered for a party, you cannot vote in the other party's primary. Only unregistered voters may, and only in one.

And typically, independent voters don't do that. As reflected in the low vote totals in the various primaries in previous elections.
