As you make clear, this is not the fault of STV; this is the fault of the
districting. Party-list PR would have the same problem as STV in a 5-seat
district - you would need over 10% of the vote to get a seat. (How much
more depends on the voting breakdown of the other parties. In a 3-party
race you will rarely need much more than 12% or so, while in a many-party
race you may need as much as 20%.) Furthermore, it may be harder to get
votes as a third-party candidate in list PR, since now there is a real
possibility of throwing your vote away if you vote for the third party and
they fail to capture a seat.
If Malta had one or two or three districts (with 60 or 30 or 20 seats) in
the country in stead of 13 five seat districts, list PR would work fine.
Just as STV would. The only issue is that STV can be cumbersome to use for
such large districts.
>What is being proposed by Malta's third party (Alternattiva Demokratika -
>the Green Party) is that on top of STV, there will be a national list PR
>(very much a modified MMP).
Interesting idea; they would also do well to propose the merging of several
districts into new larger districts.
