Is Scottish MMP being “gamed”?

As noted in an earlier comment thread, initially by Dave Hutcheson, former First Minister of Scotland, Alex Salmond, has formed a new party called Alba. It plans to run only list candidates. This has raised some questions about whether this is a “gaming” of the MMP system to enhance the majority of pro-independence parties, bypassing the compensation mechanism. For instance, a pro-independence voter could vote for the Scottish National Party candidate in their single-seat district and the Alba list.

I don’t believe this is true “gaming” in the sense of the dummy lists we have seen in MMP systems in Albania and Lesotho in the past (or even the recent Korean election), but “gaming” does not have a precise definition.

I recommend reading Dave’s comment (linked above) and then the following comment in the same thread by JD Mussel as well as the Politico story he links to. There will also be another new party entering on the pro-union side, All 4 Unity, headed by good old George Galloway (about whom I have written before, most recently under the title, “Galloway is back”; well, he’s back again!). It is similarly motivated to Salmond’s entry: to enhance the total seats for his side of the divide through encouraging tactical split voting.

Then, to get a sense of just how Alba’s entry could affect the result, Leonardo Carella has a very interesting and valuable Twitter thread, viewable in one page thanks to Thread Reader, with simulations under various scenarios.

As I said, I have my doubts this party entry is as problematic as some see it, but it is a debatable point. So, what do readers think?
