The Alaska system does sound pretty good.
I live in an open primary state which suits me fine. Sometimes it is branded as “controversial”. Example: Cynthia McKinney got primaried by another D, allegedly because a lot of GOP voters decided to vote for her opponent in the D primary. I’m OK with that, as a D was going to win that election. If you were a conservative living there, making your opinion heard at the ballot box is a good thing. Without open primary, your only option would be to vote for the GOP candidate running unopposed in the primary who would get swept in the general.
I believe something like this could happen with Marjorie Taylor Green if there is a smart GOP opponent in the next election cycle. That district will likely reelect her if she is the GOP candidate. If there is a reasonable GOP primary opponent, a lot of D voters would likely vote in the GOP primary.
