I've put together a breakdown of Scotland's 8 List regions, with the SNP's vote calculated to reflect the division implemented by AMS.

This demonstrates the ineffectiveness of SNP/SNP voting for most pro-independence supporters. The data is here:

Central region: SNP won 9/9 seats.
AMS list handicap: 9 (+1) = 10
Actual SNP list votes: 129,082 (47.7%)

List returns: 4 Labour & 3 Tory MSPs from 110,705 (40.9%) votes.

Effective SNP list vote: 16,978.
SNP list returns: 0 seats.
List returns 3 Labour and 3 Tory MSPs from 144,072 (44.7%) votes.

Scotland total:
List votes: 953,587 (41.7%)
Effective list votes in each region combined: 120,752
List total: 4/56 seats (7%)

This is how AMS operates.

This is why SNP/SNP is de facto enablement of british party MSPs.

If independence is your priority, please vote SNP/Alba.
